Like when you were kids (For example) and you secretly ate the last piece of cake secretly but your brother found out annd went straight of to your parents telling on you. A tell tale is a person that likes to tell on you to parents teachers etc. -----

That's more of a tattle tale. There was a rhyme when I was a kid, Tattle tale, tattle tale you smell. Ok, it doesn't rhyme but we sung it to someone who ratted us out for doing something silly.

Tell-tale is more like a sign not a direct statement, like a tell in Poker. It's a sign someone reads from body language, for example, that tells them something about you that you don't want them to know. Or like the Tell-tale Heart by Poe, no one else hears the heart beating, but the guilty man can't stop hearing it, the beating is a tell-tale of his own guilt.

Answer 2

A tellable tale is an easily memorizable tale. A tellable tale is also not a poem or some other literary work memorized word for word.
