This prefix is also often used before vowel sounds (that includes a/á, e/é, i/í, o/ó, u/ú as well, not just lenited f) in the past tenses (both habitual and preterite)[/i]).
I think I just came across an example of this.
I’m listening to an audio book by Kerry native speaker Sláine Ní Chathalláin called “Nain”.
And in the chapter “Muintir Nain” at around 4:30 she says “
ní dh’fhág Nain talamh na hÉireann riamh”.
I thought this was quite interesting as the usage of dh here would only show up in the new past tense system (where all the r forms are dropped), which Sláine uses.
Séamus - by your original message, did you mean that forms like ní dh’fhágfad and ní dh’fhágann do not exist?
