+ Munster Irish, plus I'm answering the questions for Cayuga, Seneca, and Irish.
(1) Does the pronoun have gender-specific forms?
For Cayuga and Seneca the pronominal prefixes have gender specific forms, yes. For Irish, yes.
(2) Is a copula verb (or suffix) used? If possible, pls underline it.
There is no form of "to be" in Cayuga or Seneca, the verb is "to teach." For Irish, it's the copula.
(3) Does the noun 'teacher' have gender-specific forms?
Yes for Cayuga and Seneca (due to their being based off of a verb form). No for Irish
(4) Does the noun appear in the dictionary form or in another case (as in Polish)?
That's hard to answer for Cayuga and Seneca; for Irish, it's the dictionary form (nom.-acc.).
