What edifies?
Not tongues!!
1Cr 14:4 He that speaketh in an [unknown] tongue edifieth himself; but he that prophesieth edifieth the church.
Speaking in tongues edifies the speaker not others. That is why IN THE CHURCH it is preferred that there be prophesy instead of tongues, unless those tongues are interpreted.
You are getting stuck on one phrase in one verse and those blinders are preventing you from understanding the topic.
I am not stuck on anything, I am just holding to what God says, and tongues today are not genuine languages.
that means they are nonsense, and no one is getting edified by the repitition of meaningless sounds and swaying back and forth and phony miracles and chanting and phony gold dust and phony laughing revival and the false idea that the US is in revival of some kind.
Sorry to roll that all into one heap, but all those things are errors that the modern Charismatic movement is involved in, not just the false spiritual gifts thing.
