Common Usage Errors
This chapter targets recurring mistakes: uncountable nouns that look plural, the two meanings of 'used to', and subjects that take a singular verb despite a final 's'.
Uncountable Nouns
Words like 'information', 'news', and 'advice' are uncountable: no plural 's', singular verb ('The news was...').
Used To
'Used to + infinitive' describes a past habit; 'be used to + gerund' describes being accustomed to something. Keep the two patterns apart.
