Over versus overly [closed]

A few years ago, I read a grammar rule about the proper use of over versus overly. After searching, I can no longer find it. My husband says it is correct to add an LY anytime you want to describe a verb. He therefore says things, such as overly cook, overly eat, overly worked,etc. I am hearing other people use these words as well. I believe the compound words, overcook, overeat, etc. would be correct here. Not only does the added LY sound unnecessary, I believe there is a rule explaining the reason.


The use of overly in the prototypical adverbial function (modifying a verb) is often at best archaic, especially with base forms. The compound verbs are indeed a far better choice.

It is however often used to premodify adjectives;

overly: to an excessive degree : TOO
