Step 1: Identify the base and derived form.
The base word is cat (a noun). By adding the suffix -y, we get catty, which functions as an adjective meaning "cat-like" or "spiteful".
Step 2: Recognize the morphological process.
- Inflection changes grammatical categories (e.g., tense, number, case) without changing the word class.
- Derivation creates a new word, often changing word class or meaning.
- Suppletion replaces a form entirely with another root (e.g., go → went).
- Reduplication repeats part or all of a word.
Here, -y creates a new lexical item (adjective), which is derivation.
