Thank you my friend
Top of the morning to you!
It sounds like a do-it-yourself translation from someone who doesn't speak Irish.
"gaelach" should be "na nGael" "Ádh mór na nGael a thabhairt duit" means "To give you good Irish luck"
"Tá" means "Is / Are" "maith" means "good "Go maithe mo chara" means "May my friend forgive" "agus" means "and" "féin" mean "self" As a complete sentence it make no sense. It's probably a poor attempt at saying "Tá mé go maith a chara agus tú féin?" which means "I'm grand my friend and howare you?"
It should be eitherDia duit, a chara. (Hello, friend) orDia daoibh, a chairde. (Hello, friends) in Irish.
It means you tried to translate 'Happy St. Patrick's day to you all' using google translator.It should be Lá Fhéile Pádraig sona daoibh go léir.
And
"mora duit ar maidin" means "good morning" in Irish.
Agus = and Cúpla = couple, twins Beag = little
Duit means "for you" in Irish, but it depends on what you are saying. Examples: "Dia duit" - a greeting (usually for "hello") literally translates and "God for you" or "God be with you". "Tá sé seo duit" is "It/This is (here) for you". 'Duit' is the meaning in 'malay language' after translate to english
Cara means friend; a chara can mean 'his friend' or when addressing someone A chara, O friend. This is Irish Gaelic.
The phrase "Lá breithe sona duit" means "Happy Birthday to you" in Irish (Gaelic).
