snidely

The word 'snidely' is built upon the adjective 'snide,' whose origins are obscure but likely emerged in 19th-century British slang. It is thought to be related to a dialectal verb meaning "to cut" or "to sneak," which metaphorically evolved to describe a cutting, sneering, or underhandedly derogatory remark or attitude. The addition of the ubiquitous Old English adverbial suffix '-ly' formally converts this descriptive quality into a modifier for actions, specifying the manner in which a critical comment is delivered. Thus, the modern sense retains the core idea of indirect, sly malice, now packaged as an adverb describing the mode of speech.
