Initialism

[pazybeloved]

I would like to know if the word initialism is used to explain abbreviations such as US or CD
Thanks

Welcome to the forum, pazybeloved.

Yes it is, apparently, though it's not a word I was previously familiar with.

See this answer to the same question on another forum:

It was new to me.

Well, it seems is not a common term as I thought, so I would use the concept abbreviation.
Thanks you all

Welcome aboard, pazybeloved.
I'm curious as to how you'd say it in Spanish. ¿Inicialismo?

Have not found an expression in Spanish just the word Sigla

Have not found an expression in Spanish just the word Sigla

Which works for both acronyms and initialisms, I should say.
