CONTENTS
This page is devoted to the irregularities of the 
third conjugation (-iyr verbs). 
 
There are two subclasses of this conjugation: IIIa, in which no form of the 
verb has an extension, and IIIb, in which verbs have an -isc- extension between 
their stem and some endings. Subclass IIIb is larger and has no irregularities. 
Subclass IIIa consists mostly of irregular verbs. 
 
Here is a list of the common verbs in this 
subclass: 
  
    | audiyr | 
     | to hear | 
     | lêviyr | 
     | to betray | 
     | serviyr | 
     | to serve 
    (something) | 
   |  
  
    | avriyr | 
     | to open | 
     | mentiyr | 
     | to lie (say 
    an untruth) | 
     | sûfriyr | 
     | to suffer | 
   |  
  
    | covriyr | 
     | to cover | 
     | mêtiyr | 
     | to measure | 
     | sûviyr | 
     | to go up | 
   |  
  
    | dormiyr | 
     | to sleep | 
     | moriyr | 
     | to die | 
     | tûssiyr | 
     | to cough | 
   |  
  
    | êixiyr | 
     | to go out | 
     | ofriyr | 
     | to offer | 
     | vêniyr | 
     | to come | 
   |  
  
    | escanciyr | 
     | to pour | 
     | partiyr | 
     | to leave | 
     | vestiyr | 
     | to dress | 
   |  
  
    | esparniyr | 
     | to spare | 
     | pêtiyr | 
     | to ask for | 
     | vinciyr | 
     | to bind | 
   |  
  
    | farciyr | 
     | to stuff | 
     | ringiyr | 
     | to snarl | 
     | xentiyr | 
     | to feel | 
   |  
  
    | fêriyr | 
     | to injure | 
     | saliyr | 
     | to go out | 
     | xerviyr | 
     | to serve 
    (someone) | 
   |  
 
Prefixed verbs formed from the above are 
conjugated analogously, e.g. compartiyr (to share), 
convêniyr (to suit), repêtiyr 
(to repeat), etc. 
 
Practically all verbs in this subclass present 
some irregularity in the present indicative. The only other verbs completely 
following the pattern of mentiyr are: partiyr, sûviyr and 
xentiyr. 
  
  - A supporting vowel is inserted in the 2nd person singular in the same 
  situations as in the 2nd conjugation. The only verbs not needing it, in 
  addition to the three completely regular ones listed above, are: audiyr (auds), 
  fêriyr (fers), mêtiyr (meits), 
  moriyr (mors), pêtiyr (pets), 
  saliyr (sals) and vêniyr (vens). 
  All other verbs in this subclass need the supporting vowel: covriyr (couvres), 
  farciyr (farces), etc.
 
  
  
  - Overall, three verbs follow 
  the pattern of simple vocalic alternation - the root vowel is different when 
  stressed and when unstressed. Example: covriyr 
  (to cover) - couvro, couvres, 
  couvre, covriym, covriys, 
  couvren.
  
  
  
  - The others in this set are: mêtiyr 
    (to measure): meito / mêtiym; 
    pêtiyr (to ask for): peto 
    / pêtiym.
 
   
  
   
  
  
  - One verb follows the pattern where only the 
  root vowel of the 1st person singular is different from that in the infinitive 
  and the other persons of this tense: moriyr (to 
  die) - môro, mors, more, 
  moriym, moriys, moren. 
  [Note that this pattern involves three vowels when looked at from the phonemic 
  point of view: /'mɔru, 'mors, 
  'morə, mu'røĭm, 
  mu'røĭs, 
  'morən/]
 
  
  
  - Two verbs combine these two spelling 
  patterns, effectively making for three alternating vowels: lêviyr 
  (to betray) - lêivo, leivs, 
  leive, lêviym, lêviys, 
  leiven; fêriyr (to 
  injure): fêiro, fers, 
  fere, fêriym, fêriys, 
  feren.
 
  
  
  - Seven verbs have no vocalic alternation, but 
  change the root-final consonant in the 1st person singular.
  
  
    
    - In three of these verbs the 
    consonant change is phonemic as well as orthographic: audiyr (to hear) - audzo; 
    esparniyr (to spare) - esparnho; saliyr (to go 
    out) - salho.
 
    
    - In the other four such verbs, 
    the change is orthographic only, due to the different ways of spelling 
    palatal consonants before back and front vowels: escanciyr (to pour) - escanço; 
    farciyr (to stuff) - farço; ringiyr (to snarl) 
    - ringio; vinciyr (to bind) - vinço.
 
  
   
  
   
  
  - One very common irregular verb has both 
  vocalic and consonantal alternation: vêniyr (to come) - venho, 
  vens, vene, vêniym, 
  vêniys, venen.
 
 
 
The forms of this tense are generally regularly 
formed from the infinitive stem: moriyr - morîa, 
vinciyr - vincîa, etc. The following exceptions 
should be noted, however: 
  
  - The five verbs with -ê- in the stem vowel 
  lose the circumflex in this tense. Example: vêniyr 
  (to come) - venîa, venîas, 
  venîa, veniam, veniais, 
  venîan. 
  
  
    
    - The other four verbs are: fêriyr 
    (to injure) - ferîa; lêviyr 
    (to betray) - levîa; mêtiyr 
    (to measure) - metîa; pêtiyr 
    (to ask for) - petîa. The verb êixiyr (to go 
    out) is not affected, as -êi- is considered to be a diphthong:
    êixîa.
 
  
   
  
   
  
  - The one verb with stem final -g, ringiyr (to 
  snarl), needs a trema in the 1st and 2nd person plural to make sure that the 
  -i- is pronounced. The full imperfect paradigm is: ringîa, ringîas, ringîa, 
  ringïam, ringïais, 
  ringîan.
 
 
 
The forms of this tense are also quite regular, 
based on the infinitive stem: moriyr - moriy, 
vinciyr - vinciy, etc. Exceptions: 
  
  - The verb vêniyr (to come) is highly irregular in this tense: veini, 
  venisti / venís, veine, 
  venim, venistes / vêniys, 
  vêniyron.
 
  
  - The four other verbs with -ê- in the stem 
  lose the circumflex in this tense as well, but only when the next syllable 
  does not contain an -iy-. The full paradigm for pêtiyr (to ask for) is: pêtiy, 
  petisti / petís, petí, petim, petistes / pêtiys, 
  pêtiyron. 
  
  
    - Similarly: fêriyr - fêriy 
    but ferí; mêtiyr - mêtiy 
    but metí; etc.
 
   
  
   
 
 
This tense is generally regular. It is formed 
by adding the endings of the tense directly on to the infinitive, with the 
additional change of the -iy- to -i- in the 1st and 2nd person plural. Sample 
pattern: 
  - moriyr (to die): moriyra, 
  moriyras, moriyra, 
  moriram, morirais, 
  moriyran.
 
 
One additional note: the 5 verbs with -ê- in 
the root lose the circumflex accent in the 1st and 2nd person plural, e.g.: 
  - vêniyr (to come): vêniyra, vêniyras, 
  vêniyra, veniram, venirais, 
  vêniyran.
  
  
    - Similarly: pêtiyr - pêtiyra but petiram; 
    fêriyr - fêriyra but feriram; etc.
 
   
  
   
 
 
These are normally regular, with the endings 
added on to the infinitive in which the -iy- has changed to -i-. Example, for 
the verb moriyr (to die): 
  
  - Future: moriroy, 
  morirás, morirá, 
  morireim, morirêis, 
  morirán.
 
  
  - Conditional: morirîa, 
  morirîas, morirîa, 
  moririam, moririais, 
  morirîan.
 
 
The 5 verbs with -ê- in the stem lose the 
circumflex: veniroy, petiroy, 
feriroy, etc. 
 
Just as for 2nd conjugation verbs, the pres. subj. of 3rd conjugation verbs 
is normally based on the 1st person sing. of the pres. ind. Example:  
  - vêniyr (to come) [venho]: venha, venhas, 
  venha, venham, venhais, 
  venhan.
  
  
    - Similarly: audiyr - audza; dormiyr - dorma; lêviyr - 
    lêiva; moriyr - môra; etc.
 
   
  
   
 
Two verbs have vocalic alternation in this tense: 
  
  - covriyr (to cover): couvra, couvras, 
  couvra, covram, covrais, 
  couvran.
 
  
  - mêtiyr (to measure): meita, meitas, 
  meita, metam, metais, 
  meitan.
 
 
 
This tense is normally regular, with the endings added on to the infinitive 
in which the -iy- has changed to -i-, and from which the -r has been dropped. 
Example, for the verb moriyr (to die): 
  - morisse, morisses, 
  morisse, morisseim, 
  morissêis, morissen.
 
 
The 5 verbs with -ê- in the stem lose the 
circumflex: venisse, petisse, 
ferisse, etc. 
 
The 2nd person singular of the imperative is identical to the 3rd person 
singular of the pres. ind., with the -e ending changed to -i:  
  - partiyr > parti, audiyr > audi, 
  saliyr > sali, covriyr > couvri, 
  vinciyr > vinci, vêniyr > veni; 
  etc.
 
 
The 1st person plural of the imperative is identical to the same person in 
the pres. subj.: 
  - partiyr > partam, audiyr > audzam, 
  saliyr > salham, covriyr > covram, 
  vinciyr > vinçam, vêniyr > venham; 
  etc.
 
 
The 2nd person plural of the imperative is identical to the infinitive, with 
the final consonant -r replaced by -t: 
  - partiyr > partiyt, audiyr > audiyt, 
  saliyr > saliyt, covriyr > covriyt, 
  vinciyr > vinciyt, vêniyr > vêniyt; 
  etc.
 
 
 
The Present Participle and the Gerund are normally regular, with the ending -ent and -endo, respectively, added to the 
normal stem:  
  - partiyr > partent, audiyr > audent, 
  saliyr > salent, covriyr > covrent, 
  vinciyr > vincent; partiyr > partendo, audiyr > audendo, 
  saliyr > salendo, covriyr > covrendo, 
  vinciyr > vincendo.
 
 
The 5 verbs with -ê- in the stem lose the 
circumflex: venent, petent, 
ferent, etc.; venendo, petendo, 
ferendo, etc. 
The past participle is identical to the infinitive, with the final consonant 
-r replaced by -t: 
  - partiyr > partiyt, audiyr > audiyt, 
  saliyr > saliyt, vêniyr > vêniyt; 
  etc.
 
 
Five verbs have irregular past participles: 
  - avriyr (to open): apert; covriyr (to cover): 
  copert; ofriyr (to offer): offert; 
  sûfriyr (to suffer): sûffert; vinciyr (to bind): 
  vint.
