Etymology

The word "gambler" originates from the verb "gamble," which itself derives from the earlier English word "gamen" (meaning "to play" or "game"). The suffix "-er" is a common English agentive suffix, turning verbs into nouns that denote a person performing the action. Thus, a "gambler" is literally "one who gambles." The term evolved in the 18th century, reflecting the rise of organized betting and games of chance in English-speaking societies.
