Tá Corcaigh sa theas. Tá Corcaigh sa deisceart. Are they both saying the same thing? GRMA

‘Tá Corcaigh sa deisceart’ is fine. ‘Theas’ is an adjective and adverb – not a noun -so you can’t say “sa theas”. Another way to say ‘C is in the south’: ‘Tá C ó dheas’, though this can also mean “to the south/southwards”. I’m not sure if ‘Tá C theas’ just on its own is ok.
