Builds up vocabulary that reflects the breadth of their experiences.
Observe whether the child: builds up vocabulary that reflects the breadth of their experiences.
What it looks like
Three ways this behaviour shows up as a child grows. Each level includes everyday moments to watch for.
Emerging
Just starting
The child sometimes uses new words after an outing or story, but the words may be short-lived, used only when prompted, or limited to one context.
What you might see
After a new experience (e.g., visit to a shop), the child refers to it only as “there” or “that place” without specific vocabulary.
The child uses broad words for many things (e.g., “thing”, “stuff”) even when specific words have been modelled.
Across several weeks, the child’s talk shows few new words connected to new events or topics.
The child repeats a new word from a book (e.g., an animal name) once but does not use it again later without a reminder.
After an outing, the child uses one new word (e.g., “bus”) but does not add other related words (ticket, driver, stop).
The child uses a new word only in one exact routine (e.g., “helmet” only when putting it on) and not when talking about it elsewhere.
Expected
On track
The child adds new words from varied experiences (books, outings, settings) and begins using them in familiar contexts, with some adult support.
What you might see
The child uses new words from recent experiences (e.g., “library”, “doctor”, “concert”) when the topic comes up again.
The child adds topic words during play (e.g., “garage”, “pump” after a petrol station trip) especially with adult prompts.
The child uses new describing words (e.g., “sticky”, “noisy”) after hearing them in context.
Exceeding
Going further
The child consistently builds vocabulary that shows a widening world (places, activities, people, objects) and uses new words spontaneously across contexts.
What you might see
The child talks about different settings with distinct vocabulary (e.g., “supermarket” vs “park” vs “nursery”) and can name what happens there.
The child brings in words from books and media into play (e.g., “map”, “treasure”, “volcano”) in ways that fit meaningfully.
The child uses new words across contexts (e.g., uses “bridge” for a playground structure and later for a book picture).
The child asks about word meanings (“What does ‘enormous’ mean?” / “What’s that called?”) and then uses the word later.
The child uses new vocabulary in explanations (e.g., “We need a funnel so it doesn’t spill”) rather than only labelling.
The child generalises a new word to a new example (e.g., learns “pattern” and later points out patterns on clothes/tiles).
Try this at home
Small everyday moments where you can notice this behaviour without setting up anything special.
After an outing (shop, park, library), ask “What did you see there?” and listen for specific new words that match the experience.
During book sharing, choose one new word (object/place/action) and notice whether your child uses it later in play or conversation.
In pretend play, set up a theme based on a recent experience (doctor, café, bus) and observe whether your child uses experience-related vocabulary spontaneously.
At mealtime, ask your child to name and describe something from their day (place, person, object) and note whether vocabulary shows variety across days.
During bath/bedtime, ask “Tell me three things you did today” and listen for distinct vocabulary rather than repeated generic words.

Development Matters in the EYFS (DfE, 2012), Communication and Language: Speaking (30–50 months).
This construct is framework-native and targets broadening vocabulary as children encounter a widening range of experiences.

A usage-based account supports vocabulary growth through repeated meaningful encounters with words across diverse social contexts.

Not Yet
Vocabulary remains narrow and tied to a small range of routines; the child often uses vague labels instead of words learned from new experiences.

The child uses broad words for many things (e.g., “thing”, “stuff”) even when specific words have been modelled.

Secure
The child consistently builds vocabulary that shows a widening world (places, activities, people, objects) and uses new words spontaneously across contexts.
The child talks about different settings with distinct vocabulary (e.g., “supermarket” vs “park” vs “nursery”) and can name what happens there.

The child uses new words across contexts (e.g., uses “bridge” for a playground structure and later for a book picture).
Reflexive
The child actively integrates new vocabulary into explanations and stories, generalises words to new examples, and may notice or ask about word meanings.
The child asks about word meanings (“What does ‘enormous’ mean?” / “What’s that called?”) and then uses the word later.
The child uses new vocabulary in explanations (e.g., “We need a funnel so it doesn’t spill”) rather than only labelling.
The child generalises a new word to a new example (e.g., learns “pattern” and later points out patterns on clothes/tiles).
