By chance I have this huge Collins table dictionary.
It gives some information as the online Ethymology gives none.

acorn, of Old English aecern; the fruit of a tree, acorn; related to Gothic akran, fruit, yield.

Date "acorn" was first used in popular English literature: sometime before 1596.

Others and betters may give you more details if you are lucky.

I must say I like your word "oaknut ".

(in my language we use the word "eikel" (acorn) as a friendly term of abuse. I think "˙ou silly oaknut" would do nicely as well. Maybe I'll use it for a change.
