If you're looking for a brief way to express "meaning" in a Latin context, you could consider these options:
* "sig." - This is a common abbreviation for "significatio" in some contexts, though it's not universally recognized.
* "s.v." - This abbreviation stands for "sub verbo," meaning "under the word," and is often used in dictionaries and glossaries to indicate the definition of a word.
* "def." - This is a common abbreviation for "definition," which could be used in place of "meaning" in some situations.
Ultimately, the best abbreviation to use will depend on the specific context and audience.
