noun / verb
whiff
WIF/wɪf/
A brief impression of something, especially through smell.
He catches a whiff of perfume from the narrow testing strip.

Etymology
The modern word was likely coined afresh for a slight puff of air or an inhalation of tobacco smoke. This fleeting-puff image connects a brief smell with the figurative sense of a faint hint.
In context
It was like a whiff of the heather-perfumed breezes of Hankley to see his homely face once more.
