'Yn y bore'
Bore da, cariad.
Yfory. Often you will only hear "fory" though, because it is easier to say "Bore fory" than "Bore yfory" (tomorrow morning).
"You are Welsh" = Rwyt ti'n Gymreig
Generally they will say good morning, which is "bore da", or good afternoon "prynhawn da" as greetings, "Hi" or "Hello" are not usually used.
Bore Da

Cymraeg
No in Welsh is dim.
"y diwedd" is how you say it in Welsh language.
