depends on idiom

What are you writing, a textbook on English?

"Any" can be followed by a singular or a plural*, but I don't think idiom has anything to do with it. It's standard grammar.

*Or uncountable noun:
e.g. any time, any luck

No, no, no. But sometimes I have to argue with my friends in English about English grammar, but the word 'xxx''s equivalent in English I haven't been able to find. In my langauge, xxx would be used in this way:

1. In grammar, you can say 'British and Japanese slangs', but according to English xxx, the usual way is 'slang', not 'slangs'.
2. According to modern English xxx, THE is not used for park names, station names, airport names, or lake names.
3. Whether ANY should be followed by a singular or a plural depends on xxx. For example, 'Are there any stamps?', not IS; 'there isn't any train', not ARE.

'Idiom' is the nearest word I can find; a direction translation of the term in my language would be 'custom method':

1. According English xxx, only 'work experience' is correct; 'working experience' is wrong.

Can you find out what xxx is? Though I suspect whether this word exists in English.

We would say: standard English, everyday English, or just usage.
There is, for example, a book called Usage and Abusage.

So is my sentence the way native English speakers would use the word?

-In/according to English grammar/everyday English/modern English usage, Britons and Americans would say.../only 'you were', not 'you was', is possible./only 'he doesn't know', not 'he don't know', is possible.

Those things are not possible in 'standard English' but there are very many non-standard dialects of English, mainly regional, spoken by native speakers, where people do say these things.

Thank you~ but...um...you forgot to check whether

-In English grammar... etc

is correct metalanguage.

I was not aware it was required.

um...let me ask again:

eg -In/according to English grammar/everyday English/modern English usage, Britons and Americans would say.../only 'you were', not 'you was', is possible./only 'he doesn't know', not 'he don't know', is possible.

Do you think a Briton or American would say the red part when commenting on a non-native's sentence? If not, what can we say?

When using standard English, Britons and Americans would say ''you were', not 'you was'.

Did you see Henning When on 8 Out Of 10 Cats Does Countdown Friday night?

I never saw that. Our American friend was over last year, and I showed her a DVD of Henning live at the Edinburgh Festival. He cracked this joke: "In Germany we have to be nasty to the Muslims because there aren't any Jews left to be cruel to". She sat bolt upright and her eyes nearly popped out of her head, and she exclaimed "I can't believe he just said that!".

what should I say?:

-Whether we have to use THE for buildings depends on ___, without definite rules. For example, we don't use THE for parks, but for river names.

The Chrysler Building
The United Nations (building)
The Bank of England

but

Windsor Castle
Grand Central Station

It's fairly obvious (to English speakers )

um...but what should I fill in on that line? Depend on ___.

Even buildings are not consistent in this case. White Hall is a building.

Whitehall is a street (where an important few buildings are located).

I can't see a consistent pattern.

For instance, we talk about the Taj Mahal or the Alhambra, but Buckingham Palace or Glasgow Central station.
Camden Market, but The Bronx.
The Pallisades, but Central Park. The Grand Canyon, but Daytona Beach.

I think you're wasting your time trying to look for a rule.

oh no, we have been talking on cross purposes. um... My question was, there's no rule about whether we need THE for buildings/architectural structures, so in explaining the thing to others, what word should I put in?:

-Whether we have to use THE for buildings depends on ___, without definite rules. For example, we don't use THE for parks, but for river names.

I thought the nearest word was IDIOM, but some of you disagreed.

Yes we did. This has already been answered. You could say standard usage, common usage, or a good phrase is "custom and practice".

Thank you~

I am arguing with my friends; what should I put in ?:

-According to English ___, if HABITAT, though listed as uncountable in dictionaries, is preceded by an animal name, THE must be used, like this:

-The government's project is destroying the Japanese dolphin habitat.

English tradition?guidance?grammar?usage? Mctag gave me several choices, but this time they don't seem OK.
