I made a connection!! When my grandson misread “have” rhyming it with “gave” — the heavens opened, the light shone, the ground trembled. Could there be a bridge between have and behave?
Longtime readers of this blog know that I get terrifically close to tipsy on be- prefix words. New readers: I can’t explain it: I just love them. Betake, benumbed, befuddled, besought, beribboned. And on and on.
Have comes from Old English habban “to own, possess; be subject to, experience”
Behave comes from be- intensive prefix + have in sense of “to have or bear (oneself) in a particular way, comport”
::Happy sigh::
Isn’t life delicious?

Noticed be-leaguer in my crossword yesterday…in context of pester. I was bedazzled.
Indeed!
I almost used “betimes” in the subject of a blog post recently 😉
You should have! I heartily approve!
Your grandson didn’t mis-read “have.” He gave it the correct phonetic pronunciation—don’t you think? Hope no one berates him for this.
True! I told him the rule-breaker was the word. And I see what you did there! Nice!
