I have a few words (amongst many) that I am really wondering about because dictionaries haven't been of much help here, so if any one can help it would be awesome!
AisRódheasModhúilli gceartAnd I know that
bhfuil is used to form questions, but what does it actually mean? And
raibh, now that I think of it! (I have some guesses, but they don't work in all context.)
Any help on any of these would be great!!

Dia's Muire dhuit, a Anabeth.
ar ais is "back"
ródheas is "too nice" but probably just means "very nice" in an older context.
modhúil is "mild, gentle, modest"
i gceart can be "right" or "well" or "properly"
téimse "I'll go"
réitithe is the past participle of "réitigh". We'd probably have to see the context to give you a meaning for it, as
réitigh has many meanings.
Tá/níl is a mixture of two verbs,
tá and
fuil.
Níl comes from
ní fhuil =>
ní 'uil =>
níl. The question form of
fuil is
an bhfuil, dependant form
go bhfuil/
nach bhfuil, etc.
Similarly, the past tense
bhí/ní raibh is a also mixture of two verbs
bhí and
raibh.
Hope that makes sense.
