I felt the smile creep onto my face. What does smile creep mean? What about synonyms?
This is an expression that describes the lips slowly moving into a smile. Usually used in a literary context to indicate that some realisation or understanding is dawning upon the protagonist.
"Smile creep" is not a noun. You do not use it in the same sense as "I felt the CREME on my face."
Shorten the phrase to "The smile creeps onto my face." and it makes more sense. Subject= smile, verb= creeps, "my face" is the object.
Creep = to move slowly.
So the above sentence means, essentially, "I felt the smile move slowly onto my face"
Another example: I had to creep quietly into the room to keep from waking the baby.
