IPA: //ˈtruːpʃɪp//
KK: /ˈtrupˌʃɪp/
A type of ship designed specifically to carry soldiers and military personnel to different locations.
The army deployed a troopship to transport the soldiers to the training camp.
Troopship is formed from "troop" (from Old French *troupe*, meaning a group or company of soldiers) and "ship" (from Old English *scip*, meaning a vessel for traveling on water). The word refers to a ship designed to transport troops or soldiers.
Think of a 'group of soldiers' ('troop') being transported by a 'vessel' ('ship') — that's what a troopship does.
