All, most, some, any, no/one

These words are quantifiers and pronouns. They tell us how much or how many of something we are talking about. They can be used before nouns (as determiners) or alone (as pronouns).

• Use all, most, some, any, no/one to express quantity or to refer to people or things.
• Some and any are often used with countable and uncountable nouns; their use depends on whether the sentence is positive, negative, or a question.
• No/none and no one indicate the absence of something or someone; choose the correct form for people (no one) vs things (none/no).

Remember how context affects which word to use:

• Use some in positive sentences and when offering or requesting: 'I have some information.' / 'Would you like some coffee?'
• Use any in questions and negative sentences: 'Do you have any updates?' / 'We don't have any copies.'
• Use no to mean 'not any' before a noun: 'There is no time.' Use none to replace a noun: 'None of the time was useful.'
• Use no one to refer to people (singular meaning): 'No one is available.'

Think: offers/affirmative = some; questions/negatives = any; no/none = absence

Watch out for these universal errors:

• Using 'some' in a negative sentence instead of 'any' (e.g., 'We don't have some copies.' → wrong).
• Confusing 'no' and 'none' placement: 'No employees attended.' vs 'None attended.'
• Using 'no one' with plural verbs (remember 'no one is', not 'no one are').
• Using 'all' without 'of' when a pronoun follows incorrectly (correct: 'all of them', not 'all them').

Check sentence type (affirmative, negative, question) and the noun (people vs things) before choosing the quantifier.
