A type of plant that has soft, cotton-like fibers, often found in weedy areas.
The cottonweed grew abundantly in the field, attracting many insects.
Cottonweed is formed from "cotton" (from Middle English *cotoun*, meaning soft fiber from the cotton plant) and "weed" (from Old English *wēod*, meaning a plant or herb). The word refers to a type of plant that resembles cotton or has cotton-like qualities.
Think of 'cotton' as a soft fiber and 'weed' as a type of plant. This helps you remember that 'cottonweed' refers to a plant that has qualities similar to cotton.
