Requests for Finnish etymologies

A good use of caution. Words found in Finnish + Karelian + Veps alone would often include recent Russian loans, similarly Finnish + Karelian + Estonian would rake in lots of Swedish and even some Low German loans.

"I usually create Proto-Finnic pages if I feel confident enough that the term comes from Proto-Finnic." Isn't that called "guessing" by another name?

The caution I described here is supposed to avoid guessing, and make sure that there is enough evidence for the reconstruction. If all Finnic languages agree on a form, there's no room left for guesswork.
