- unstable (adj.) early 13c., "apt to move," from un- (1) "not" + stable (adj.). Similar formation in Middle High German unstabel. Meaning "liable to fall" is recorded from c. 1300; sense of "fickle" is attested from late 13c. An Old English word for this was feallendlic, which might have become *fally.
