Basque verbs are generated by the infinitive of the verb you want to conjugate followed by the auxiliary-conjugated-form.
This form depends on the actions of the subject:
1. NOR - NORI: (who - to who)
The subject does something to someone/something
(John speaks to Peter)
2. NOR - NORK: (who - of who)
The subject does something to someone/something of someone/something
(John reads Peter's book)
3. NOR - NORI - NORK: (who - to who - of who)
The subject does something that affects someone/something of someone/something
(We give a present to the sister of Peter and Paul)
There are 7 persons for each conjugation:
It means that you have 7x7 actions for the first and second group (NOR - NORI and NOR - NORK ) and 7x7x7 actions for the third group(NOR - NORI - NORK).
This is an example of the third group.
The verb is 'igurtzi' and in this particular case the action goes from us (5 th person) to the sister (4 th person) of Peter and Paul (7 th person).
The conjugation of the verb is 'igurtzi bazenizuete' or 'igurtzi bazenizkizuete'.
