Child groups words into categories and understands how words relate.

Why it matters
Understanding word categories and relationships — examples of a group, synonyms, antonyms, and shared traits — deepens vocabulary into a connected network. This supports comprehension, reasoning, and the precise use of words.

What mastery looks like
- Sorts objects or words into categories, such as putting tools together or naming several farm animals.
- Identifies shared characteristics among things, such as noting that cats and dogs are both furry with four legs.
- Identifies common antonyms, such as up and down, and a synonym for a very familiar word.
How to observe it
- Can the child give several examples of a familiar category, such as animals or vehicles?
- Does the child notice opposites or near-synonyms, such as big and gigantic?
Accessibility
- Offer picture cards or real objects so children can sort without relying on spoken labels.
- Pair category words with signs or AAC symbols for children who use them.
- Children who are DLLs may categorize most readily in their home language.
