askance

The origin of 'askance' is uncertain, with several plausible theories. One prominent suggestion is that it derives from the Italian phrase 'a schiancio,' meaning 'aslant' or 'obliquely,' which entered English in the 16th century. Another theory posits a connection to the Old French 'esquancer,' meaning 'to turn aside.' Regardless of its precise source, the word's core logic has consistently pertained to an indirect or oblique angle, both literally (a sideways glance) and figuratively (a look of suspicion or disapproval). This semantic stability, from a physical orientation to a metaphorical attitude, illustrates how a word of obscure origin can acquire a precise and enduring role in the language.

This word is considered unsegmentable into productive morphemes in modern English. Its origin is obscure, but it is likely a loanword or formation whose internal structure is no longer analyzable.
