means The room in a home or building where food is prepared and cooked.

from From Old English 'cycene,' borrowed from Latin 'coquina' or 'cocina' (a kitchen), which grew from 'coquere,' to cook — the same root that simmers under 'cook,' 'cuisine,' and 'concoct.' So the word carries heat in its bones: a cousin to nearly every cooking term in Europe, all tracing back to a Latin verb meaning simply 'to apply fire to food.'
