Ετυμολογία

Borrowed from Middle Low German slû, whence probably also Dutch sluw. Further origin uncertain. Probably from a Proto-Germanic *slūhaz (“sneaking, creeping”), perhaps ultimately from Proto-Indo-European *(s)leuǵ (“to crawl, slide”), if the original sense referred to sneaking and sliding. Related with Dutch sluiken (“to creep, smuggle, act clandestinely”).
In spite of the near-identity in meaning and form, English sly is in all likelihood not related.
