scowling

The word 'scowling' originates from a Middle English verb, likely borrowed from a Scandinavian source such as the Old Norse skūla, meaning "to be furtive" or "to skulk." This root carried a sense of looking at someone darkly or with suspicion from a place of concealment or gloom. Over time, the meaning shifted from the furtive act of lurking to specifically describe the facial expression associated with such a mood—a dark, angry, or sullen frown. The addition of the '-ing' suffix, a common Germanic participle ending, transforms the action into a descriptor for the person wearing the expression or the expression itself, completing the journey from a verb of stealthy movement to a noun and adjective for a glaring look.

It functions as the core verb/root meaning to frown gloomily. ing: A suffix from Old English -ende (present participle) and -ung (verbal noun). In this word, it forms the present participle, which functions as an adjective or a gerund/noun.
