多少 vs. More or Less

On the surface, the English phrase “more or less“ looks like it should be the equivalent of the Japanese word 多少 (“tashou“, made up of the kanji for “many“ and the kanji for “few“).
“More or less“, for some reason, means “mostly“. However, 多少 means “a little“, i.e. the almost direct opposite of the English phrase. Funny, eh? Yeah, alright, maybe not that funny.
