precocious: [17] Precocious means etymologically ‘pre-cooked’. It was borrowed from Latin praecox, a derivative of the verb praecoquere ‘cook in advance’, which was a compound formed from the prefix prae- ‘before’ and coquere ‘cook’ (a relative of English cook and kitchen). But coquere was also used metaphorically for ‘ripen’, and so praecox also meant ‘early-ripening’ – whence English precocious ‘developing before its time’. The apricot is etymologically the ‘precocious’ fruit.
