more or less, kinda, sort of

"Más o menos" does mean "more or less" but maybe it could mean something else, depending on the context.

You can say "more or less", people will understand and that express doesnt feel foreign, at least in the United States. This might be because our English is also influenced by the Spanish native speakers (this assertion is base on personal experience and not backed with any research). Another way, easier way, would be just to say "about". For example, "That apple is about 1 dollar." I hope I answered your question,
