In the sentence "she keeps on looking at me",why is it okay to use looking though the word 'keeps' implies habitual action?
Is 'looking' in the sentence a verb?
"To keep on" is a phrasal verb which means "to continue." "Looking" is not used as a verb in this sentence, but rather in the gerund form.
As a native English speaker, I would add to this that "to keep on looking" is an informal expression, most commonly used with verbal expression, not written.
