Stress

Mostly initial stressed, secondary stress on the last syllable

Consonants cluster after long vowels are valid, thus those syllables are super long syllables.

non-initial syllables start always as vowels

hundraða > hundr - að - a

Umlaut-Vowel Harmonization(latter affects former)

i-mutation/u-mutation front vowel mutation/back vowel mutation

i-mutation:(i/j lead) former vowel advances while roundness remains

  • a > e
  • á > æ
  • o > ø
  • ó > œ
  • u/ju > y
  • ú/jú > ý
  • ǫ > ø
  • au > ey

u-mutation:(u/v lead) former vowel gets more roundness

  • a > ǫ

  • á > †ǫ́ > á

  • e > ø

  • é > œ

  • i > y

  • í > ý

    for these four vowels e, é, i, í, the round process are rather irregular and not common

  • unstressed a > u

Condition: when i/u appears in the suffix, the conjugation or declension of N/V/Adj will apply i/u-mutation

Some u-mutation happens where u is absent, because the u dropped at a rather early time

Consonant Sound Change

Consonant lengthening

-t/r after long vowel stem will be long (-tt/-rr)

Consonant simplification

Cluster plus consonant where the presuming result has long consonant after consonant will get shortened

fagr + -rar > fagrar

Consonant assimilation

Five major rules:

  1. -r assimilates former l/s/n when they are in a long syllable

    sæl + -r > sæll

    væn + -r > vænn

  2. -ð- assimilates former ð and generates -dd-

    eyða > †eyðði > eyddi

    -ð- also assimilates former t/s(sometimes also k) and generates -tt-/-st/-kt-

    setja > †setði > setti

    kyssa > †kysði > kysti

    kneikja > †kneikði > kneikti

  3. -ð/d- assimilates latter -t and generates -tt-

    kaldt > kaltt > kalt

  4. -nn- sometimes is assimilated by -r and generates -ð

    mann + -r > maðr

    annar + … > ann(a)r + … > aðr…

  5. -k- + -ð- generates -tt-

    sœkja > †sókði > sótti

    þykkja > †þókði > þótti

Unvoiced end

Consonants cluster in the end first become unvoiced, and then get assimilated, mostly in past tense conjugation.

-nd > -tt-

-ng > -kk-

-ld > -lt

Consonant dropping

Unstressed -n-/-l- sometimes drops before -t

mikil + -t > mikit

búin + -t > búit

Other Sound Change

Syncope and contraction

Syncope: unstressed short vowel drops

himin + -i > himni

Contraction: when an unstressed vowel followed by a stressed vowel(say AB), there is a contraction

  • if A and B are both front or back(except úa/óa and sometimes úu), they merge and generate a long vowel

    *fáa > fá

  • if A is back and B is front, they remain as untouched

    búinn

  • if A is front and B is back, they generate diphthong

    *féar > fjár(with vowel fracture)

    *knéum > knjám/knjóm

Vowel fracture

*e > ja

Other lengthening or shortening

  • stressed vowel at end are lengthened

    þu > þú

  • although long vowels before consonants cluster are valid, long vowel are often shortened before cluster, especially before long consonants

    eitt + -gi > ekki

*Retention of semi-vowel

Beginning j in Proto-Germanic drops. So beginning j in Old Norse came from fracture.

Old Norse ungr - Old English geong

Before front vowel i/y/ø/œ and sometimes e, middle j drops. In other situation, if j is after g/k or a short syllable, j retains.

veljum - velið(†veljið)

j after long vowel becomes i, this also happens when j is after a short syllable ended with g.

i-stem noun when after a long syllable stem ended with k/g becomes -j- before -a/u in suffix.

Beginning w(v in icelandic) in Proto-Germanic drops when l/r is after.

Old Norse líta - Old English wlitan

Before rounded vowel u/y/o/ø/œ, w drops.

verða > Past tense urðu/Past Particle orðinn

Old Norse œpa - Old English wēpan

After ó/ú, w drops.

Old Norse glóa - Old English glowan

At end or before consonant, w also drops.

Middle w when after g/k or a short syllable retains.

Morphology

Verb conjugation

Category:

  • 3 grammatical persons
  • 2 numbers: single, plural
  • 2 tenses: present, past
  • 3 moods: indicative, subjunctive, imperative
  • 2 voices: active, middle(like reflexive verb)

Strong Verb(Ablaut, from PIE)

Seven categories where the former six are quite regular:

Category-Infinitive-(3sg.pre)-3sg.pst-3pl.pst-(3sg.pst.sub)-p.p.

  1. bíta ’bite’-bítr-beit-bitu-biti-bitinn
  2. skta ’shoot’-skýtr-skaut-skutu-skyti-skotinn
  3. bresta ’burst’-brestr-brast-brustu-brysti-brostinn
  4. bera ’bear’-berr-bar-báru-bæri-borinn
  5. reka ’drive’-rekr-rak-ráku-ræki-rekinn
  6. fara ’go/fare’-ferr-fór-fóru-fœri-farinn

3sg.pre is closely related with infinitive, and 3sg.pst.sub is definitely the result of i-mutation of 3pl.pst.

So we regard infinitive, 3sg.pst, 3pl.pst and p.p. as :one:/:two:/:three:/:four: vowel representative respectively.

  • infinitive without -a is :one:
  • 3sg.pst is :two:
  • 3pl.pst without -u is :three:
  • p.p. without -inn is :four:

Third strong conjugation

Basic: e/i > a > u(y) > u/o and the stem is always with a double consonant ending. i is the product of e followed by n(but brenna ’burn’ and renna ’run’ is special). o is the product of u followed by l/r.

Special:

  • v drops before o/u

    verða ’become’ > verð-, varð-, urð-, orð-

  • -nd > -tt, -ng > -kk and -ld > -lt in single past

    binda > †band > batt

    gjalda ’pay’ > gjalt

  • in infinitive and plural present, ja is fractured from e when e is followed by a consonant cluster that starts with a l/r.

    †gelda > gjalda > single present: geld, geldr, geldr plural present: gjǫldum

  • infinitive with a -va ending applies u-mutation first, thus a > ǫ, i > y, e > ø. And -va was wholly removed when applying :three: and :four: types.​ -v drops when no suffix or -r is added.

    †sekkva > søkkva ’sink’

    søkkv-, sǫkkv-, sukk-, sokk-

    sg.pre søkk, søkkr, søkkr

    †singva > syngva ’sing’

    singv-, sangv-, sung-, song-

    sg.pst sǫng not sǫkk, because actually there is a -v- in the end

  • irregular verb

    finna ’find’

    finn-, fann-, fund-, fund-

    bregða ’hasten’

    bregð-, brá-, brátt, brá-

infinitive: søkkva ’sink’

dictionary: søkkva, sǫkk, sukku, sokkinn

:one: søkkv:two: sǫkkv:three: sukk:four: sokk

indicative:

  • single present
    • 1st person: søkk
    • 2nd person: søkkr
    • 3rd person: søkkr
  • plural present
    • 1st person: søkkum

Imperative

  • you: søkk
  • we: søkkum
  • you(pl.): søkkvið

Infinitive: søkkva

Present Particle: søkkvandi

Past Particle: sokkinn

Fourth strong conjugation

Basic: e > a > á(æ) > o/u, infinitives have l/m/r/n as an ending

very regular

bera ’carry, bear’ > bar > báru > borinn

nema ’take’ > nam > námu > numinn

since the fourth type is very similar to the fifth type, we cover them together.

Fifth strong conjugation

Basic: e > a > á(æ) > o, infinitives have any consonant except l/m/r/n as an ending

Special: some infinitives end with -ja, thus i-mutation causes e > i which is retained in all present conjugations. -ja verbs are like -va verbs.

†beðja > biðja ’ask, demand, bid’

†setja > sitja ’sit’

There are two even more irregular -ja verbs(which are caused by double consonant gg):

liggja ’lie(lie down)’ > †laggj(which is expected to be :two:) > lá > lág

þiggja ’accept’ > þá > þág

vega > vá > vág

More confusing examples are infinitives with v in root, like sofa and vefa:

sofa ’sleep’

root: svef-

single present: sef(søf), sefr(søfr), sefr(søfr)

plural present: sofum, sofið, sofa

single past: svaf, svaft, svaf

plural past: sváfum, sváfuð, sváfu

vefa ’weave’

root: vef-

single present: vef, vefr, vefr

plural present: vefum, vefið, vefa

single past: †vaf > óf, óft, óf

plural past: ófum, ófuð, ófu

Another irregular verb is troða ’tread’, with pattern o > a > á > o

In the end, considering verb sjá ’see’, which is highly irregular:

infinitive: sjá ’see’

dictionary: sé, sjá, sá, sé

:one: sé:two: sjá:three: sá:four: sé

indicative:

  • single present
    • 1st person: sé
    • 2nd person: sér
    • 3rd person: sér
  • plural present
    • 1st person: sjám
    • 2nd person: séð(sjáið)
    • 3rd person: sjá
  • single past
    • 1st person: sá
    • 2nd person: sátt
    • 3rd person: sá
  • plural past
    • 1st person: sám
    • 2nd person: sáuð
    • 3rd person: sá(sáu)

Subjunctive

  • single present
    • 1st person: sé
    • 2nd person: sér
    • 3rd person: sé(sjái/sjáir)

    • 2nd person: sæið
    • 3rd person: sæi

Imperative

  • you: sér
  • we: sjám
  • you(pl.): séð(sjáið)

Infinitive: sjá

Present Particle: sjándi

Past Particle: séður

Sixth strong conjugation

Basic: a(e) > ó > ó(æ) > a/e, e in past particle is the result of ending k/g.

Special:

  • some ending g drops, like in the first and second types

    draga ’drag’ > dró

  • some ending nd acts weirdly, where n drops and d gets assimilated and produces ð:

    standa ’stand’ > stóð > stóð > stað

  • some -ja words lead i-mutation, thus all the present conjugations are affected:

    sverja

    hefja

  • like fifth type, structure like v + back vowel will lose v in past conjugations:

    sverja > sór, sórt, sór

    vaxa > óx, óxt, óx

    vaða > óð, ótt, óð

  • other irregular verbs:

    slá ’slay’ > slóg > slóg > sleg

    single present: slæ, slær, slær

    plural present: slám, sláið, slá

    single past: †slag > sló, slótt, sló

    plural past: slógum, slóguð, slógu

    deyja ’die’

    single present: dey, deyr, deyr

    plural present: deyjum, deyið, deyja

    single past: dó, dótt, dó

    plural past: dóm, dóð, dó

Seventh strong conjugation

Those that cannot fit into any of the former six types are called the seventh type strong verbs. They includes:

a > á > ó

a > e > e

á > é > é

au > jó > jó

ei > é > é

The past forms of those verbs retain so-called reduplicated symbol in Proto-Germanic, which in return changes the pattern by adding initial consonant right before the root, thus producing such weird results.

Old English hātan(German heißen) > past tense †heht- > hēt

The typical patterns are as below, where :one: accords with :four:, and :two: accords with :three::

Type 1: heita ’be called’ > hét > hétum > heitinn

Type 2a: auka ’increase’ > jók > jókum > aukinn

Type 2b: búa ’inhabit’ > bjó > bjuggum > búinn

Type 3: falla ’fall’ > fell > fellum > fallinn

Type 4: láta ’let’ > lét > létum > látinn

Type 5: blóta ’offer’ > blét > blétum > blótinn

There are also other extreme irregular ones that belong to the seventh type, their conjugation are as follows:

ganga ’go, walk’ > geng(single past gekk-) > geng > geng

single present: geng, gengr, gengr

plural present: gǫngum, gangið, ganga

single past: gekk, gekkt, gekk

plural past: gengum, genguð, gengu

fá ’hand over, get’ > feng(single past fekk-) > feng > feng

single present: fæ, fær, fær

plural present: fám, fáið, fá

single past: fekk, fekkt, fekk

plural past: fengum, fenguð, fengu

halda ’hold’ > held(single past halt-) > heldum > haldinn

single present: held, heldr, heldr

plural present: hǫldum, haldið, halda

single past: helt, helzt, helt

plural past: heldum, helduð, heldu

hǫggva ’hew’ > hjó > hjuggum

single present: høgg, høggr, høggr

plural present: hǫggum, hǫggvið, hǫggva

single past: hjó, hjótt, hjó

plural past: hjuggum, hjugguð, hjuggu

Some words even retain the reduplicated forms:

róa ’row’

single present: rœ, rœr, rœr

plural present: róm, róið, róa

single past: rera, rerir, reri, where e can be ø

plural past: rerum, reruð, reru, where e can be ø

sá ’sow’

single present: sæ, sær, sær

plural present: sám, sáið, sá

single past: sera, serir, seri, where e can be ø

plural past: serum, seruð, seru, where e can be ø

snúa ’turn’

single present: sný, snýr, snýr

plural present: snúm, snúið, snúa

single past: snera, snerir, sneri, where e can be ø

plural past: snerum, sneruð, sneru, where e can be ø

gróa ’grow’ and gnúa ’rub’ have nothing to do with róa and snúa in the ancient times, but due to analogy they are both now conjugate like róa and snúa respectively.

Weak Verb

Weak verbs plus -ði- to form past tense, and according to the vowel in the stem, weak verbs can be divided into three groups.

sigl-i/j-

kall-a-

lif-i-

the former vowel is called root vowel and the latter one is called stem vowel which differs with groups.

Common sound changes in weak conjugation
  • deletion of i

    i in ði vanishes before vowel

    stem vowel i/j or i drops before -ði-

  • u-mutation(pay attention to unstressed a > u)

    kall-a-ði-um > †kalluðum > kǫlluðum

    tal-i/j-ði-uð > †talðuð > tǫlðuð

  • -ð + ð- > -dd-

    auð-i/j > eyða

    eyð-ði-a > eyðða > eydda

  • sometimes -n + ð- > -nd-

    munu ’will’ : mun-ði > mundi

    but stefna > stefnði

  • -t/s + ð- > -tt/st

    flut-i/j > flytja

    flytj-ði-a > †flytða > flytta

    þeys-ði-a > †þeysða > þeysta

  • sometimes -p/k/f/l + ð- > -pt/kt/ft/lt

    þurfa ’need’: þurf-ði-a > †þurfða > þurfta

    but hafa ’have’: haf-ði-a > hafða

  • -Cdd/Ctt > -Cd/C

    senda ’send’: send-i/j-ði-a > †sendða > senda

And we only need three representatives for weak verbs because the past tense of weak verbs share the same stem not like in the strong case. Thus infinitive, 3sg.pst, p.p. are :one:/:two:/:three:.

First weak conjugation

Stem vowel: i/j, when final syllable is short, j is chosen, otherwise i is chosen.

And i is retained in both present and past, but j is only retained in present. Notedly, whenever there is a i/j in the stem vowel slot, i-mutation is applied, therefore both present and past forms in i’s case are mutated while only present forms are mutated in j’s case.

var-i/j- > ver-j- > var-

sigl-i/j- > sigl-i- > sigl-i-

skil-i/j- > skil-j- > skil-

stafn-i/j- > stefn-i- > stefn-i-

sát-i/j- > sæt-i- > sæt-i-

Some special cases:

  • long syllables with k/g endings, -i- turns to -j- before a/u

    lág-i/j- > 3pl.pre †lægia > lægja

  • short syllables with g endings, -j- turns to -i- before single consonant or nothing in present tense.

    sag-i/j- > 1sg.pre †segj > segi

  • some short syllables with g endings may double g in present tense

    lag-i/j > legg-j-

Second & Third Weak Conjugation

Second: -a- may drop if it is followed by a vowel, sometimes it turns to -u- due to u-mutation

Third: -i- may drop if it is followed by a vowel. And it differs from the first type because the -i- here does not trigger i-mutation. -i- in the third type does not show up in the past tense.

Special: verbs with -á ending drops and only drops -i- in 3pl.pre and don’t need to supply any -a

ná ’reach,get’:

single present: nái, náir, náir

plural present: náum, náið, ná

single past: náða, náðir, náði

plural past: náðum, náðuð, náðu

Preterite-present Verb

This type of verbs apply past tense pattern of strong verbs in their present tense and conjugate as weak verbs in past tense. Only 10 in Old Nose.

How does this weird conjugation pattern exist? Because generally past tense conjugation in Proto-Germanic came from perfect aspect in Proto-Indo-European, but in those words above the perfect aspect became present tense inversely, thus their blank past tense were filled by weak conjugation pattern.

Sometimes they even have present infinitive and past infinitive.
