Etymology: The adjective in question derives from the verb "agitate," which entered English in the early 17th century, originally meaning to set in motion or disturb physically. This verb itself comes from the Latin "agitare," a frequentative form of "agere," meaning "to drive" or "to do." The frequentative form implies repeated or vigorous action, which captures the sense of stirring or stirring up. The suffix "-able," used to form adjectives, arrived in English through Old French during the Middle Ages and typically means "capable of" or "susceptible to." Combining it with "agitate" produces a term meaning "capable of being agitated" or "easily stirred or disturbed." Though the base verb "agitate" has been well established for centuries, the adjective formed with "-able" is far less common and somewhat rare in usage. It follows a typical pattern of English adjective formation but has not gained wide currency, perhaps because other adjectives like "agitated" or "restless" have filled the lexical niche more naturally. In summary, this descriptive form is a straightforward product of English word-formation processes, pairing a Latin-rooted verb with a common adjectival suffix to indicate susceptibility to agitation or disturbance.
