Definition: In English, "diminutive" refers to a person or thing that is smaller in size than its more dominant counterpart.
The word originated from Greek (διμήνητον) and means "smaller than." In this context, it could also mean "more fragile," which is why the term was chosen for a diminutive form. It's often used as a compliment to someone who is smaller or has a smaller stature.
For example:
She had the smallest nose in the room.
He had a smaller brain than I do.
Your sister is the smallest of all, not me!
