You might be right
'S dòcha gur e an fhìrinn a th' agad
Read this conversation. If you have a friend who's also learning Gaelic, you could read it together!
Tha mi a' smaoineachadh gur ann air an trèan(a) a thig iad.
I think they'll come by train [lit. that it's on the train they'll come].
Ach, nach biodh am plèana na b' fhasa dhaibh?
But wouldn't the plane be easier for them?
Cha bhitheadh. Chan eil an stèisean faisg air an taigh agus saoilidh mi gur e am plèana as cosgaile cuideachd.
It wouldn't (be). There isn't a station near the house, and I think the plan is the most expensive as well.
'S dòcha gur e an fhìrinn a th' agad an sin. Tha am plèana fada nas cosgaile.
You're probably right there (lit. it's the truth you have there). The plane is much more expensive.
