Word Origin & Etymology

The marine fish sense is adapted from the Portuguese word 'garoupa', which itself was likely borrowed from a South American Indigenous language (such as Tupi). The less common sense of one who organizes things into groups is a transparent English derivative from the verb 'group' and the agentive suffix '-er'.
