Fewer vs. Less, Then vs. Than
Fix two common usage errors. Read a concrete example, examine the trade-offs, and try a small exercise to see whether the principle applies to your situation.
Understand the language rule
- Start here. Fewer normally modifies countable items and less uncountable amounts.
- Add context. Than signals comparison; then relates to time or sequence.
- Keep in mind. Natural language has exceptions, so use these as reliable defaults.
See it in context
“Fewer chairs” usually refers to countable objects, while “less water” refers to an uncountable quantity. “Than” is a comparison word; “then” describes sequence or time. Short examples make the distinctions easier than lists of definitions.
A good usage guide explains why a word fits a sentence while acknowledging ordinary language patterns.
Mistakes and exceptions
Usage conventions include exceptions and fixed expressions, such as “less than five miles.” Overly rigid rules can produce unnatural edits.
Practice with your own text
Draft one sentence with fewer/less and another with then/than. Replace the doubtful word and ask whether the underlying comparison or sequence changes.
