In what tenses, if any, is the f ever pronounced as an f?
I can't think of any, at least in Connemara.
Does every dialect combine the conditional verb form with pronoubs, or do some places keep the two words separate?
The conditional conjugations that use analytic forms (separate pronoun) are the third-person singular and the second-person plural; the other conditional conjugations use synthetic forms (combined with the pronoun). These happen in all dialects.
