Veinlet → It is formed from "vein" (from Old French *veine*, meaning a channel or duct) and "-let" (a diminutive suffix meaning small). The word "veinlet" refers to a small vein or a minor channel in a structure.
Think of a 'small channel' — 'vein' refers to a channel, and '-let' means small. A veinlet is simply a small vein.
