Why is there no "plural" in the case of a 30 years old man? I don't get it.

This is your question, 001.


He is a 30-year-old man.

a ( article) 30-year-old ( This is an adjective here) man ( noun)

30-year-old <--------- It is a hyphenated adjective.

I hope you understand that is an adjective. Thank you!

The most appropriate word is difference

e.g. There is at least 10 years' of age difference between the husband and his wife.

=================================================================

That's how we say it over here. A very common expression in both Australia and America.

You may want to consider using "apart":

example:
John and Tom are 10 years apart in age.
or simply: John and Tom are 10 years apart.

Also, instead of using 10 years, a common usage is "decade"

example:
John and Tom are a decade apart in age.
or John and Tom are a decade apart.

In England, we usually say:

There is a 10 year age gap between ABC and XYZ.

or

There is a 10 year age difference between ABC and XYZ.

用 older 已經可以表示年齡距離；
I am ten years older than he.
I am ten years his senior.

Difference will best fit for the case and precise for this question.
e.g. We have 10-year difference in ages./ 10 years age difference.

i'd prefer to use '10 years age difference'

"there is a 30 year old man"
You can rewrite this sentence like "the man is 30 years old".
Both sentences are acceptable.

You can also write "I have a ten year old dog" or "I have a dog which is ten years old".

No matter the sentence starts with is or have, you can use either "years" or "year".

Distance is a wrong choice. As you already know, distance is a noun we used to measure a 2-3D RANGE between 2 measurable points. It's not intended to describe time. And I have never heard of anyone who uses "distance" in such way.

For age difference, the most common way to describe is your first choice------------ 10 years gap

An age gap carries absolutely no negative meaning. Don't worry. It's very commonly used.

If you want a more formal (but dumb) way, you may say "Age difference"

2009-02-01 01:35:51 補充：
Gap and difference carry the same meaning, so it doesn't really make sense if you put them in the same sentence.

You may say, "This relationship has a ten years gap(age difference)."

Why is there no "plural" in the case of a 30 years old man? I don't get it.

For the sentence, 'I (have) a ten year old dog?', people will still understand you, but it's grammatically wrong. It's a direct translation from Chinese. 我有一隻十歲大的狗。 But in english, you should really say, "I have a dog that is 10 years old." Or "My dog is 10 years old".

有的建議都是對的﹐但係實質上﹐你會唔會咁用﹖﹗

好似廣東話﹐如果你好簡單可以講出口﹐"佢地差十歲﹗"
你會唔會改用另一句話, "佢地年紀上的差距係十年" ????

後句你唔可以話佢文法上有錯﹐但係實質上有無人會咁用﹖ 學習語言﹐vocabulary and grammer 是要注意﹐但是勿忽略語言最重要的功用。

簡潔﹐通用的溝通便是最好的溝通了。 不用轉牛角尖﹐在不必要的地方上面。
