The Spanish word 'gerenta' meaning 'female manager' comes from the masculine form 'gerente' (manager) with the addition of the feminine suffix '-a'. The word 'gerente' itself derives from the Latin present participle 'gerens' (managing, carrying out), which comes from the Latin verb 'gerere' meaning 'to carry out' or 'to manage'.

This etymology shows how Spanish created a specific feminine form for this professional title by following the common pattern of adding '-a' to masculine nouns ending in '-e' to create their feminine counterparts.

Some related Spanish words include 'gestión' (management), 'gestionar' (to manage), and 'gestor/gestora' (manager, administrator). These words share the same Latin root 'gerere' and maintain similar meanings related to management and administration.

Several English words are related to 'gerenta' through the Latin root 'gerere', including 'gesture' (originally referring to the way one carries oneself), 'digest' (to 'carry apart' or break down food), 'suggest' (to 'carry from below' or bring up an idea), and 'register' (originally meaning to 'carry back' or record). The word 'gerund' (the -ing form of verbs) also comes from 'gerere', as it was seen as the form that 'carried' the action of the verb.
