Does "weak form and strong form" mean the form of pronunciation?
The following information is quoted from English Grammar Today-Cambridge:
Some as a determiner has two forms: a weak form and a strong form. The forms have different meanings.
Weak form some/ səm/ We use the weak form of some in affirmative sentences and in questions (usually expecting the answer “yes”), when the quantity is indefinite or not important (we use any in questions and negative sentences):
e.g I’ve got some/ səm/ water. e.g Have you got some water? (expecting the answer "yes")
We use the weak form of some only with uncountable nouns and plural nouns:
e.g I'm looking for some advice.(+uncountable noun)
We don't use weak form some with singular countable nouns:
e.g If you're looking for a book to read, I can recommend 'Animal Farm'
Not: If you're looking for some book to read.....
Strong form some/ sʌm/ The strong form of some is stressed. This form contrasts with others or all or enough:
[FONT=新]e.g Why do some people live longer than other people? (some, not others)
We can use this strong form to refer to someone or something particular but unknown, especially with singular countable nouns:
e.g Some idiot driver crashed into the back of me.
