What is snidely? How to use in English

The word "snidely" has its origins in the 16th century. It comes from the Old English words "snyd" meaning "a sneer" and the suffix "-ly" which forms an adverb. Initially, "snidely" meant "with a sneer" or "sneeringly". Over time, the meaning evolved to convey a sense of sarcasm, irony, or subtle mockery. In the 17th and 18th centuries, the word was often used to describe someone's tone or manner, implying that they were speaking or writing with a subtlety that belied their true intentions. In modern English, "snidely" is often used to describe a comment or remark that is intended to be humorous but comes across as biting or snarky. Today, "snidely" is often used to add a sense of nuance to someone's tone or language, implying that they are being subtle but also slightly mischievous in their words.
