The word "Squiny" is a rare and archaic term that means "to cast a sidelong glance or squint." Its spelling can be a bit confusing, but it's pronounced as /ˈskwɪni/ (SKWEE-nee). The "squ" at the beginning of the word is a combination of the consonants /skw/, and the vowel sound in the middle is an "i" pronounced as /ɪ/. The final "y" is a typical way to create an adjective from a noun, as in the word "sneaky."
The word "squiny" does not have a well-established etymology, as it is considered a slang or dialect term, and its origins are unclear. However, it is often used to describe someone who is suspicious or doubtful. It is believed that "squiny" might be related to or derived from words such as "squint" or "squinny", which refer to a cross-eyed or squinting gaze. This association with skepticism or distrust could have influenced the development of the term. Nevertheless, due to its informal nature, its true etymology remains uncertain.
