2. He grew slightly last year.
3. He grew much last year.
4. He grew a little last year.
5. He grew in a medium degree last year.

(Are the expressions grammatical? Would you mame more expressions similar to them?)

Answer 1

Numbers 3 and 5 are not generally used. The others are grammatical. \

You can also say, He is much taller than he was last year. He is not much taller than he was last year. He is just a little taller than he was.
