Of a quiet, modest, unassuming, reserved nature. Somebody who is serious or sober (moderate, self-controlled) and even shy. For most of the 1800s, this was
the ideal for a woman, as
illustrated in Jane Austen's works and the works of many poets, writers, artists, and leaders. Not
necessarily a doormat, but certainly a docile, gentle kind of persona.
The boy next door was enraptured by the ingenue, a shy, demure thing with big doe eyes and a sweet
disposition.
He was a demure, unpretentious
young man with his feet planted
on the ground.
