junky

The word 'junky' is a relatively modern English formation. Its core, 'junk,' has a murky etymology, potentially tracing back to the Latin juncus for a rush plant, whose dried stems were of little value. By the 19th century, 'junk' solidified in English to mean old, discarded materials or worthless items. The adjectival suffix '-y,' of native Germanic origin, was appended to create a term meaning "characterized by junk." Initially describing cheap or shoddy goods, its application shifted in the early 20th century to describe a person characterized by worthless, addictive substances, i.e., a drug addict, which became its primary meaning.

Structure: junk (useless things) + y (characterized by) junk: Origin uncertain, possibly from Old French junque (old rope) or Latin juncus (rush plant). In English, it came to mean old or discarded material. Functional role: Core root denoting worthless items. y: A suffix of Old English origin, used to form adjectives meaning "characterized by" or "full of."
