Resembling or characteristic of a ferret; small and wiry, or persistently inquisitive and probing like a ferret.
Formed from 'ferret' with the adjectival suffix '-y,' which describes something as being like or having qualities of the noun (similar to 'catty,' 'ratty,' or 'mousy').
You might describe a person with small darting eyes, restless energy, or relentless curiosity as having a 'ferrety' quality—the adjective captures an entire behavioral profile in one word, which is why animal adjectives are so handy in English.
