word knowledge
Is it normal that my child is not yet showing word knowledge?
Between 3 and 7, children build word knowledge at very different paces, and one skill being slow is usually within normal range. By 3 most understand more than they say; by 5–6 they explain and learn words fast. Seek a developmental check if several signs cluster — very few words, hard-to-understand speech, trouble naming things — or if words are lost. This guides early support, not a diagnosis.
If you're watching how your child understands and uses words, and wondering whether you should be worried yet — that careful noticing is exactly the kind of attention that helps children thrive.
In short
Between 3 and 7 years, children build word knowledge at very different paces, and a single skill being slow to appear is usually within normal range — not a cause for alarm. By around 3 years most children understand far more words than they can say, follow simple two-step instructions, and name familiar people and objects; by 5–6 they explain, ask questions and learn new words quickly. If your child is broadly tracking this — even if vocabulary feels behind a sibling or a friend — that is often simply their own timeline. A check becomes wise if several signs cluster together or if you notice a loss of words once used.What to watch
Word knowledge grows alongside listening, attention and play. Gentle flags worth a clinician's eye:- Understanding — at 3, not following simple instructions or not pointing to named objects in a book.
- Using words — very few words by 3, or not joining two words together; speech that even family struggle to understand by 4.
- Connecting ideas — by 5–6, real difficulty naming everyday things, recalling words, or understanding question words (who, what, where).
- Any regression — losing words or understanding once clearly present. This always deserves prompt review.
These point towards a developmental check, never a label. Hearing should also be checked, since it quietly shapes every word a child learns.
The science
Vocabulary develops through everyday talk, shared books and play — receptive understanding always runs ahead of spoken words. Wide individual variation is normal and well documented in milestone guidance; what matters is steady forward movement, not matching a chart exactly.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list. Our clinicians build your child's own baseline and shape support around strengths. Learn more about word knowledge and how our speech therapy team offers gentle, play-based support.Trusted sources

What to watch
Seek a developmental check if, by 3, your child follows few simple instructions or has very few words; speech even family can't understand by 4; real trouble naming everyday things or understanding question words by 5–6; or any loss of words or understanding once present. Have hearing checked too.
Try this at home
Narrate your day out loud — name what you see, do and feel as you go. Read one short picture book daily and pause to ask 'where's the dog?' before naming it yourself. Everyday talk is the richest soil for word knowledge.

Frequently asked
How many words should my child know at age 3?
Most 3-year-olds understand many more words than they speak and use a few hundred spoken words, naming familiar people and objects and following simple instructions. There is wide normal variation — steady growth matters more than an exact count. If words are very few or family can't understand speech, a developmental check is wise.
Could a slow vocabulary just be my child's own pace?
Yes — children build word knowledge on very different timelines, and one area being slower is often simply their own pace, especially when understanding is strong. A check becomes helpful if several signs appear together, or if your child loses words they once used.
Should I get my child's hearing checked?
It's a sensible first step. Hearing quietly shapes every word a child learns, so a hearing check alongside a developmental review helps make sure nothing is being missed.
