What does approb mean?
Saw a manga that used “approb” as translation of SFX. Translator I believe is non-native.

approb is likely short for approbante, which is a scholarly borrowed Latin term meaning “with approval of”. So the translator likely intended to convey a sense of scholarly approval or backing for her performance.
I can’t find a source justifying this translation.
