"Outtell" Natural Recordings by Native Speakers
I apologize, but "outtell" is not a word in the English language. It's possible that it's a typo or a nonstandard term. If you meant to say "outtell" as a verb, it doesn't exist. However, if you meant to say "out tell", it would mean to reveal or make known something that was previously hidden or secret.
Outstrip means to surpass or exceed someone or something in speed, distance, time, ability, or performance. It can also imply that someone or something is going beyond what is expected or required.
