Question

If you say now he is grown up, would it be "grown up" or "grown-up"

Answer 1

It would be grown up.
"Grown-up" (with a hyphen), is a noun, therefore you only use it in the following context:
He is a grown-up.
Grown up can also be a verb as in the following context:
He has grown up.
Therefore, you do not say 'he is grown up'. It is either 'he has grown up' or 'he is a grown-up'.

Answer 2

The correct form would be either or the following:


"He is grown up"

or

"He is a grown-up"

Answer 3

The hyphen goes between multiple-word adjectives when they precede the word that they are modifying. We don't use a hyphen, however, if one of the modifiers is an adverb ending in -ly.

Examples
The bride and groom rode through town in a horse-drawn carriage.
The employee at the hardware store recommended a carbon-tipped saw blade.
Joan was glad that her saw blade was carbon tipped.
Ben knew the most effective door-to-door sales techniques.
After he graduated from college, Ben sold kitchen knives door to door.
Notice that "carbon tipped" in sentence 3 and "door to door" in sentence 5 do not have hyphens, because they do not come directly before nouns.

Answer 4

grown up. grown-up would be a noun , like "that person is a grown-up".

Answer 5

GROWN-UP if it`s a noun
grown up if it`s a verb
so:
he is a grown-up
or he has grown up

Answer 6
