Is …?

A bheil …?

There are a couple of grammar points we need to take into consideration.

It is clear that this sentence follows the Gaelic language structure  Verb | Subject and we have enough names or pronouns and place to fill in the blanks .

A bheil … à … ?
Is / are … from …?
A bheil … às … ?
Is / are … from …?
A bheil i às an Eadailt?
Is she from Italy? 
A bheil Ruairidh à Steòrnabhagh?
Is Derek from Stornoway?

We know that from becomes  à / às  dependent on whether the Gaelic place name has a definite article  An | Am | A’ ( or the  in English).

We know how to ask the question, but do we know how to answer? Yes, we do. Answering a question in Gaelic is dependent on how it is asked, so listen carefully when someone asks. 

Tha
Yes (literally is)
Chan eil
