A creak is a harsh, squeaking sound, like an old door. A creek is a small stream of water. Memory hook: creak has an a for audible, since it is a noise, while creek has the double e of a wet, flowing stream.
The core difference
Creak is a grating sound (or the verb for making it), while creek is a small stream or inlet.
- creak — a squeaking or grating sound: She heard a creak on the stairs and froze.
- creek — a small stream or narrow inlet: The kids spent the afternoon wading in the creek.
How to tell them apart
Creak is both a verb and a noun. Floorboards creak, and the sound they make is a creak. The word is imitative, meaning it was shaped to sound like the noise it describes.
Creek is always about water: a small stream, or a narrow inlet, often one that runs to the sea. Because the two are pronounced the same, the error appears in stories, such as a gate that creeks. If a sound is involved, use creak.
