OFTEN when we use only adjective, it means moderate degree. for eg- he is handsome. here it means to a moderate extent. now if i take the literal meaning of the word handsome as only of moderate degree, then the phrase'very handsome' wont make sense, as 'handsome' itself means of moderate degree

The use of adjectives in language is not always literal and can vary based on context. In your example, "handsome" does not necessarily mean "of moderate degree". It is a qualitative adjective used to describe someone's physical appearance, often implying more than average attractiveness.

When you add "very" before "handsome", you are intensifying the degree of handsomeness. So, "very handsome" means that the person is extremely or exceptionally attractive, more than just moderately attractive.

In English, it's common to use intensifiers like "very", "extremely", "exceptionally" etc., before adjectives to emphasize or strengthen the degree of the adjective. So, the phrase "very handsome" does make sense in English language usage.
