The same as you do in English.
This noun doesn't exist in French. Maybe you would mean "bête"? "Bête" is a beast or an idiot.
"Life is joy" in French is "la vie est joie."
It wouldn't change. It would still be Elisabeth. Actually it would, pronunciation wise it would be Elizzhabett. No french name as Beth i have ever heard of. :-)
Je suis tres heureux
la joie dans le matin
Je m'appelle......is how you say my name is.......in French.
My name is (whatever) is "Mon nom est ..." or "je m'appelle ..." in French.
probably "la joie de ma vie"
Same way just with alittle accent
It's not a French name
It's not a French name
Beth ydy enw ein ysgol ni? or Beth yw enw ein hysgol ni?
