Etymology
The word 'jumper' is a transparent compound built from the verb 'jump' and the agent suffix '-er'. The verb 'jump' itself is of uncertain origin but likely arose in the 16th century as an onomatopoeic imitation of the sound or motion of a leap, possibly influenced by similar words in other Germanic languages. The suffix '-er', with its ancient lineage from Latin '-ārius' via Proto-Germanic, is one of the most productive in English for forming agent nouns. The semantic journey from 'one who jumps' to items of clothing is an example of functional metonymy; the 'jumper' sweater (originating in the 19th century) was likely so named because it was a loose garment one could 'jump into' easily, or perhaps associated with the athletic activity of jumping. The electrical 'jumper' wire performs the function of making a connection 'jump' across a gap.
