Conjuntions: You treat these like you do in english, but the second part of the sentance may change.
Agus/ Is (like the iss in miss): And
E.G. Tha I luath agus l`aidir (lie-jeer) (She is fast and strong).
Tha me ag iarraidh Isbeanean is buntata (I want sausages and potatoes).
In: Ann an
E.G. Tha an Cu ann an taigh (the dog is in the house)
Note: Gh's are silent at the end of gaidhlig words as are dh, th, and the h silent when gh begins a word. U is often OO, but sometimes it is like the U in "Sun", more an uh.
This complexity is the result of the current alphabet, which plain doesn't work for gaidhlig, but has to be coped with.
But: Ach
E.g. Tha me ag iarraidh a cadal, ach tha cus fhuaim ann. (I want to sleep, but there is to much noise).
Some Question terms.
A Bheil e/i: Is it/she/he...
E.g. A bheil e math? (a veil eh ma): Is he/it good?
Cuin a bheil...?: When is...?
E.g. Cuin a bheil dadaidh a tighinn? When is dad coming?
There are no words for yes and no in gaidhlig, so you use context related answeres.
Chan eil...: It isn't (happening/existing)...
Cha Bhi...: It isn't (going to happen)...
Bhi...: It is (going to happen)...
Tha...: It is (hapenning,existing)...
Sometimes it is accepteble to use just "Bhi", "Chan eil" or "Cha Bhi" on their own
