Word Origin & Etymology

Derived from the Ancient Greek 'parasitikos', from 'parasitos' (literally 'one who eats at the table of another'), combining 'para-' (beside) and 'sitos' (grain or food). In classical antiquity, the term originally referred to a social flatterer who earned meals through wit before adopting its biological meaning in the 17th century.
