Fòram na Gàidhlig

There's a lot of that happening in English too - you just don't notice, because you're used to it

From context only.

'S e do bheatha

Since your name is pronouncable in Gaelic, a Lionda. See how I inserted an o in there to fix the spelling according to Gaelic rules? I didn't even thing about it, my fingers did it for me

Is tusa Lionda.
Sin thu fhèin, a Lionda!

You use the article with most country names (some exceptions are Alba, Sasainn, Èirinn, Breatainn), but not with cities, unless those city names are real Gaelic words. So, Tha mi à Turin. "Tìoraidh" is Gaelic spelling for "Cheerie" ;), and people say "Tìoraidh an-dràsta"...

You need the dative both after "ann an" and "anns an". The "s" in "anns an" is a marker that you're using the article there.

Rule of thumb: always use the dative after a preopsition. There are some exceptions where you use the genitive though.

Good advice

In English, you can just raise your voice to put emphasis on a word, and the stress system is pretty intricate. You can't do that in Gaelic at all, so you have to use grammatical devices like extra words instead. 'S ann is one of those devices.

Transcriptions are correct. The bh used to be pronounced historically (which is why "Inbhir Nis" is "Inverness" as pronounced by English speakers, with a v), but in the modern dialects, it gets dropped.

Yes, the only difference in pronunciation is that mhath is nasal, you don't really hear the final th. People often mix up bh and mh, I just wanted to make sure that you didn't fall a victim to one of these well-meaning but harmful sites.

You're pretty close, but the answer is "neither". I'd for /ɤi/

Coibhean /kʰɤivən/
Coibheantìn /kʰɤivənˈtʲʰi:n/

The second name violates the spelling rule, and also Gaelic stress which is always on the first syllable (unlike Irish). you could go for Coibheintin or Coibheantan instead.

Halo, Ionatain!

BTW ... is ainm dhomh is Irish. We say "Is mise X"

That's correct, but you mixed up mhath ("good" lenited) with bha ("was"). Beware of random websites - there are a bunch out there that have "Slàinte bha" as a phrase on them which is completely wrong, and they all copied the mistake from each other. Some of those sites ...
