Usage

1 A small, seemingly innocent word, as is so frequently misused (or not used where needed) that interested writers are advised to consult a full-length usage guide for counsel on its proper use. As is often used in causal senses in place of because or since ( As Julie wasn’t hungry, she ordered only a cup of coffee); in such constructions, where as may cause confusion, it is generally advisable to use the unambiguous because, or since. 2 On whether it is more correct to say he’s not as shy as I rather than he’s not as shy as me, or I live in the same street as she rather than I live in the same street as her, see personal pronoun (usage). 3 For a discussion of when to use as rather than like, see like1 (usage).
