Can I use "at morning" in the following sentence. "Did you have more work at morning ". I read some where that "at" specifies during any morning and "in" specifies during particular morning. My doubt here is generally we tell like "I go for a walk in the morning" .The statement which I written in blue is quite controversial to me. Can someone explain this with examples.
No, we don't say "at morning." The text in blue is incorrect.
