There is nothing aimless about a big cat on the prowl.

Imminent lethal intent. Focused. Targeted. Stealthy.

Although I understand completely why the various ways we use prowl made the list of roam synonyms, the word’s essential meaning makes it an antonym to every synonym since linger.

Prowl is a word with purpose, weapons locked. A black panther in the darkness, preparing to pounce.
