delicate: [14] Delicate comes either from Old French delicat or direct from its source, Latin dēlicātus, but its ultimate history is obscure. Its formal similarity to delicious and delight, and the fact that ‘addicted to pleasure’ was one of the meanings of Latin dēlicātus, suggest that the three words may have an ancestor in common. Delicatessen [19] was borrowed from German delikatessen, plural of delikatesse ‘delicacy’, which in turn was acquired by German from French délicatesse.
