Primary school flashbacks! :)
And what would "that is mine" be?
Is liomsa é sin.
Thank you ^^
Why isn't "He is with me" also a correct solution?
That would be Tá sé liom, or Tá sé liomsa if you prefer.
Why ' It is me ' incorrect?
"Liom" is possessive. You are saying it belongs to you. So it is "mine" not "me"
Go raibh maith ahat!
so if is liomsa é translates as 'he is mine', how does one say 'I am his'? Would that be 'Is leatsa mé'?
“I am his” would be Is leis-sean mé.
That would be "I am yours." I suppose one could say, "Is leis mé," but I amn't convinced that's a construction one would use about people.
Why is "It belongs to me" wrong? It is the same thing.
