If you mean a fin like a fish fin, there is a word, but mostlly each one is different; Lā (fin). Anal fin, kuaalo. Caudal fin, hiʻu. Dorsal fin, kualā. Pectoral fin, etc. If you mean fin, like 'the end', it is pau'ana.
"Este fin" = this end
La fin means la fin it doesn't really mean anything at all. Sorry hope it helped
"The End", means "Fin", in English.
That depends, do you mean fin at the end of a cartoon or comic?
