Here are some other words that can be used depending on the context:
* ברענען (brenen) - literally "to burn", used for the act of burning itself
* אש (ash) - meaning "ashes" or "cinders"
* פלאַם (flam) - meaning "flame"
It's worth noting that Yiddish often uses metaphors and idiomatic expressions. So, the specific word for "fire" might change depending on the situation.
