Describing Material
To say something is made of clay, always use the word 'de' before 'arcilla', as in 'un plato de arcilla'.
The Gender of Arcilla
This word is feminine, so you use 'la arcilla' or 'una arcilla'. Unlike some words starting with 'a', the stress is on the second syllable (ar-CI-lla), so the article doesn't change.
Clay vs. Mud
Mistake: “Using 'arcilla' to describe the mud on your shoes after rain.”
Correction: Use 'barro' for generic mud. Use 'arcilla' specifically for the fine-grained earth used by artists or builders.
