two-meter high

[tulipflower]

Is it correct to say this is a two meter height wall?

Or we can just say this is a two meter high well?

 

[Matthew Wai]

This is a two-meter high wall.
This wall is two meters in height.

Is it correct to say 'This is a two meter height wall'? No.

This is a two[no hyphen]meter high wall.

This wall is two meters in height. ​This is grammatical but not natural, Matthew.

This wall is two metres high.

 

[Matthew Wai]

This is a two[no hyphen]meter high wall.

I am confused because a hyphen is used in 'a ten-foot high statue' ── quoted from http://www.ldoceonline.com/dictionary/high

Fair enough.

That's correct. We hyphenate when the two (or more) words are used together as an adjective. We also remove the pluralising "s" from the end of the noun involved.

The wall is two metres high.
It is a two-metre high wall.

The boy is six years old.
He is a six-year-old boy.

The bed is six feet long.
It's a six-foot long bed.

As you can see in the last one, changing the plural back to the singular completely changes the word, from "feet" to "foot". It's an irregular plural.

I'd be even inclined to apply another hyphen in:
It is a two-metre-high wall.
It's a six-foot-long bed.

I'd be even inclined to apply another hyphen in:
It is a two-metre-high wall.
It's a six-foot-long bed.

That's how I'd write it, too. The hyphenated ensemble is a compound adjective.

Absolutely right. I was concentrating so much on the "six-foot" part of it that I neglected to continue hyphenating where it was necessary. Thanks.
