flush

Definitions

The origin of flush is uncertain: it may go back to Latin fluere (flow) like the rest of this family, or to a French/imitative source (fluche) suggesting a sudden gush. Either way the core idea is a sudden rush — of water (flush a toilet) or of blood to the face (flushed cheeks).

Why It Means This

Note: flush is filed under flu, but its etymology is genuinely uncertain — it may descend from fluere or from an unrelated French/imitative word for a sudden gush. We keep it here because the meaning (a sudden flow) fits the family, but we are not claiming a confirmed link to fluere.
