From Portuguese tanque (“tank, liquid container”), from an Indo-Aryan language, likely Gujarati ટાંકી (ṭā̃kī, “cistern”) or Marathi टांकी (ṭāṅkī). A false friend can be found in North Germanic: dunk (“canister, keg”), 17th c. tönk, which appears derived from both Low German tunneke, Dutch tonneke (diminutive of "barrel"), and dunka (“to dunk, to dip under water, to moisten”). * In the sense of armoured vehicle, prototypes were described as tanks for carrying water to disguise their nature and due to physical resemblance. First attested in 1915, but in common usage only as of 1916. Displaced landship, and mostly displaced battlewagon.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
