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

From Middle English rokki, rokky (“rocky”), from rok, rokke (“rock; a rock or stone; large rock by a coast or in the sea; rocky outcrop on a mountain, cliff; castle, citadel, stronghold”) [and other forms] + -i (suffix forming adjectives). Rok, rokke are derived from: * Old English *rocc (“rock”); and * Anglo-Norman roc, roce, roque, and Old French roce, roke, roque, variants of roche (“rock”); both from Medieval Latin roca, rocca; further etymology uncertain, possibly of Celtic origin. The English word is analysable as rock + -y (suffix forming adjectives meaning ‘having the quality of’).

adj

Easily rocked; unstable. · Encountering many problems; difficult, troubled; also, in danger or distress. · Of a person: ill, or unsteady (for example, as a result of a shock).

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

From rock (“to move back and forth”) + -y (suffix forming adjectives meaning ‘having the quality of’). Rock is derived from Middle English rokken (“to move (something, such as a cradle) back and forth; to move or sway back and forth in an unstable manner; to go”) […], from Old English roccian (“to rock”), from Proto-Germanic *rukkōną (“to move; to move back and forth, rock”), ultimately from Proto-Indo-European *h₃rewk- (“to dig; to till (soil)”).

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.
