Use 'Some' Safely
Context is King
Smart Tips
Ask yourself: 'Can I have two of these?' If yes, add an 's'.
Remember 'Many' has 4 letters (like 'count') and 'Much' has 4 letters (like 'mass'). Wait, just remember: Many = Countable, Much = Uncountable.
Most abstract nouns (love, peace, knowledge) are uncountable.
If you want a serving, use 'a'. If you want the substance, use 'some'.
発音
Plural S
The 's' in countable nouns can sound like /s/, /z/, or /ɪz/.

文化メモ
British English often treats collective nouns like 'team' or 'government' as plural, unlike American English.
Americans strictly use singular verbs for collective nouns.
In professional settings, using 'some' instead of 'a' for uncountable nouns is seen as more precise.
The distinction traces back to Old English, which inherited Germanic noun classes.
