The Spanish word 'psicóloga' (female psychologist) comes from combining two Ancient Greek roots. The first part 'psico-' derives from the Greek word 'ψυχή' (psyche) meaning 'soul' or 'mind'. The second part '-logo' comes from the Greek 'λόγος' (logos) meaning 'word' or 'study'. When these elements combined, they formed 'psicólogo' (male psychologist), and adding the feminine suffix '-a' creates the feminine form 'psicóloga', meaning a female practitioner who studies the mind.

Several common Spanish words share these Greek roots. Words beginning with 'psico-' relate to the mind or psychology, such as 'psicosis' (psychosis), 'psicoanálisis' (psychoanalysis), and 'psicoterapia' (psychotherapy). Words ending in '-logo/-loga' indicate someone who studies or specializes in something, like 'biólogo/bióloga' (biologist) or 'sociólogo/socióloga' (sociologist).

English speakers can easily connect 'psicóloga' to many familiar English words that share the same Greek origins. The most obvious is 'psychologist', which is a direct equivalent. Other related words include 'psyche', 'psychology', 'psychic', and 'psychotherapy'. The '-logy' ending in English words like 'biology', 'sociology', and 'technology' also comes from the same Greek root 'logos', meaning 'study of'.
