Sacudir, Spanish for “to shake” comes from the Latin for the same, quatere.
From that same root, we get a bunch of English -cussion words, including:
- Discussion — that’s when you shake up what you’re talking about!
- Concussion — that’s when you shake someone so hard, they get hurt!
- Percussion — that’s when you shake the drums a lot!
You can see the s‑c in reverse in the Spanish sacudir and the -cussion words.
