Learn English – Difference between “on the both sides” and “on both sides”

I think eatable is more often used to mean palatable.

eatable sample usage

Whereas edible is more often used in relation to plants etc that are not poisonous.

edible sample usage

But there is an overlap.

(I learnt the sample usage trick from Anthony Quinn)

The main different would probably be the pitch and length of the sound.

When I think "scream", I'd mainly think of a long, loud cry.

When I think "shriek", I'd mainly think of how high-pitched the cry is.

I'm easily able to imagine a short shriek, but a short scream doesn't come to me so easily. It just turns into a "shout".

Hope this helps.
