It seems like so often it is the language of orgin for most english words, along with spanish as well. I’m told there are many languages it has influenced, so how could it die?

Linguistically, it helps you learn more about another language. Historically, it helps you understand literature and other cultural factors in the society that spoke it. Pragmatically, there are professions that require basic knowledge of a dead language (e.g., law, medicine, priesthood, etc.)

We all know the meaning for abbreviation…
“a shortened or contracted form of a word or phrase, used to represent the whole.”
Then why the word abbreviation itself is too long?
This is the answer! Abbreviation, in itself, is not an abbreviation! (abbr. is the abbreviation for abbreviation I think!) , so obviously it is not going to be small, and concise, but more of a broad word. Obviously, many words in the English language derive from Latin words, or are similar to Latin words: thus, the long word “abbreviation” starts from the short word ‘brevis’ meaning ‘brief’.
Well! Any funny answers?
Star and rate if you like!
