Are you sure, that you learn the right language? Gaelic (Irish) does not have such a word - at least I can't find it in my dictionary. (I even think, that the letter "Q" does not exist in Gaelic) Google tells me that the word “Quérote” is Galician (Galego) - Maybe you mixed that up. ;-) In Irish "I love you" (I am in love with you) means: "Tá mé i ngrá leat" ;-) Fáilte romhat!

Other ways of saying "I love you" are "Tá grá agam duit" (singular) or "Tá grá agam díobh" (plural). Both phrases literally mean "I have love for you".
