A synonym is a word that means the same, or almost the same thing, as another word. This tag is for asking about pairs of words. If you're requesting a synonym, please use the ‘single-word-request’ tag.
A synonym is a word that means the same, or almost the same, as another word.
Some lexicographers reject the idea that any two (or more) words have exactly the same meaning, usage, and connotation.
No perfect synonyms
Different words that are similar in meaning usually differ for a reason; e.g. feline is more formal than cat. Long and extended are only synonyms in one usage and not in others; for example, a long arm is not the same as an extended arm.
