That should be "Is tosach maith leath an obair". It means "A good start is half the work"
In Irish, Is maith liom mo... is 'I like my...'inhala is not an Irish word.
It looks like google translate cannot accurately translate into Irish.
It's leathbhróg and mean 'One of a pair of boots/shoes'. Also used to mean 'Of divided allegiance/double-dealing'. (Irish Gaelic).
It's 'Go raibh maith agat, a chara' and means 'Thank you, friend' in Irish.
Apparently another incorrect google translation "I like to do cause you think".
"Tá tusa an-mhaith ar fad" means "You're great all together"
Did you mean math? Don't recognize the word "Maith". Math is Matemática in portuguese...
"tú féin chomh maith" means "yourself as good"
"Ní maith liom é seo" means "I don't like this"
It can mean 'life, time, world'. Period of existence. State of existence. Conditions of life of a period. Way, or sphere of life. The world of enjoyment. The world of human affairs. All creation. All people. (Expressing totality)
"Féidir do bheannaigh lá chomh maith" means "can your greeting day as good"
