drained

The word 'drained' originates from the Old English verb 'drēahnian', meaning to filter or strain liquid. This term is related to the Old English 'drēahn', meaning a strainer, and finds a deeper connection to the Proto-Germanic 'draug-', implying drying or becoming dry. The modern sense evolved from the literal process of liquid being drawn away from a place, leaving it dry. By the 16th century, this concrete meaning extended metaphorically to describe a person whose energy or resources have been completely withdrawn, leaving them exhausted. The suffix '-ed' transforms the past action of draining into an adjective describing the resultant state, whether of a dry container or a fatigued individual.
