Source etymology 2

Original entry ↗
verb

Preceded by the dummy subject it: to have strong winds and usually lightning and thunder, and/or hail, rain, or snow. · To make (someone or something) stormy; to agitate (someone or something) violently. · To disturb or trouble (someone). · To use (harsh language).

noun

A violent assault on a fortified position or stronghold.

Selected source glosses provide context, not a complete modern definition inventory

The verb is derived from Middle English stormen (“of the wind: to blow violently; to cause to roll or toss”), from storm (noun) (see etymology 1) + -en (suffix forming the infinitives of verbs). Compare Middle English sturmen (“to attack (someone) with great force”), from Old English styrman (“to rage, storm; to make a great noise, cry aloud, shout, storm”), from Proto-West Germanic *sturmijan (“to storm”), from Proto-Germanic *sturmijaną (“to storm”), from *sturmaz (“a storm”) (see etymology 1) + *-janą (suffix forming causatives from strong verbs, with a sense of ‘to cause to do [the action of the verb]’). The Middle English word did not survive into modern English. The noun is derived from verb etymology 2, verb sense 2.3 (“to violently assault (a fortified position or stronghold, a building, etc.) with the aim of gaining control of it”). Cognates * Dutch stormen (“to bluster, storm”) * German stürmen (“to rage, storm; to assault, attack”) * Icelandic storma (“to storm”) * Low German stormen (“to storm”) * Swedish storma (“to bluster, storm”)

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.
