Etymology
Origin of sidelong
Explanation
A sidelong glance or facial expression is directed toward one side, and it's also usually skeptical or suspicious. If your brother promises to clean the whole house, you might react with a sidelong look at him. Sidelong can be used as an adjective or an adverb, so you can give your friend a sidelong glance when she starts reading the wrong paragraph aloud in English class, and you can also look sidelong at the kid beside you who's asleep and snoring at his desk. The adverb is older, and it comes from the Middle English sidlyng.
