the.com/garbage truck

means A truck that collects household waste from curbs or bins and hauls it off to disposal or recycling sites.

from Straightforward compound: 'garbage' entered English in the 1400s originally referring to the waste parts of a butchered animal — giblets, entrails — before widening by the 1600s-1700s to mean refuse of any kind, its deeper roots uncertain though possibly tied to Anglo-French terms for sifting or waste grain. 'Truck' as a motor vehicle is a 19th-century sense built on an older word for small wheels or carts. Put them together in the early 20th century, once motorized collection replaced the horse-drawn dust cart, and you get the plainly named marvel that, against all odds, became a toddler's favorite celebrity.
