John Gill Commentary 1 Corinthians 14:10

"There are, it may be, so many kinds of voices in the world, and no [kind] is without signification." — 1 Corinthians 14:10 (ASV)

There are, it may be, so many kinds of voices
(anvl) , "tongues", or "languages", as the Syriac version renders it; that is, as many as there are nations in the world; there may be seventy of them, as the Jews say there were at the confusion of languages at Babel; there may be more or less:

and none of them is without signification :
every language, and every word in a language, has a meaning in it, an idea annexed to it, which it conveys to him that understands it, and that cannot be done without a voice ordinarily speaking.
