Making a dull, heavy sound; moving with heavy, solid sounds; a verb form describing something hitting with a thump.
From 'thud,' which is onomatopoeia (a word that imitates the sound it describes). First recorded in the 1600s to represent the sound of something heavy hitting something solid.
Onomatopoeia words like 'thud' are awesome because they try to make language sound like real sounds—your mouth literally makes a dull sound saying 'thud.' Different languages have different onomatopoeia because they hear sounds differently!
