How would someone say “My favourite…”?

[ElliotBizarre]

There doesn’t seem to be a word for favourite (not that I’ve found, at least). However, “jatne emuurir” means “prefer”, so would that just be used instead?

Yeah, that would mean something akin to "best choice". Use jate'shya instead of jatne if you want it to be comparative instead of superlative.
