"Is maith léi aisteoirí."
Translation:She likes actors.
léi (pronounced lay) is how you normally say it it however léithí (pronounced layhee) is the emphatic way of saying it: Is maith léi aisteoirí- she likes actors Is maith léithí aisteoirí- SHE likes actors
The emphatic form of léi is léise. Are you sure that léithí isn’t a non-emphatic variant form of léi ? (Dinneen listed léithe as a variant form of léi.)
It seems some speakers do put an /h/ in there: http://www.fuaimeanna.ie/en/Recordings.aspx?Ortho=l%C3%A9i
How would you know whether the word 'aisteoiri' is referring to actresses or actors?
