word knowledge
When to escalate delayed word knowledge in a child
Word knowledge grows on a wide timeline, so single-month variation is normal. A frontline health worker should escalate when a child shows no words by 18 months, no two-word phrases by 24 months, doesn't follow simple instructions, isn't pointing or responding to their name, or has lost words once used. Always include a hearing check, and act on a red flag plus parental concern rather than waiting — early referral gives the best results.
A frontline worker who notices a child's words aren't growing as expected is already doing the most important job — catching it early, with care.
In short
Word knowledge — understanding and using words for everyday things — grows on a broad timeline, so single-month variation is normal. As an ASHA or PHC worker, escalate for a developmental check when a child shows no words by around 18 months, fewer than 10–15 words by 18 months, no two-word phrases by 24 months, doesn't follow simple instructions, isn't pointing or responding to their name, or has lost words they once had. These are reasons to refer, not a diagnosis — and early referral gives the best results.What to watch
Use these practical age markers during home visits and growth-monitoring days:- By 12 months — no babbling, no gestures (waving, pointing), no response to name.
- By 18 months — no single words, or doesn't seem to understand simple words for familiar people and objects.
- By 24 months — fewer than around 50 words, no two-word combinations ("more milk"), can't follow a one-step instruction.
- Any age — loss of words or skills the child previously had, or a parent who is worried.
Also check hearing history (ear infections, no startle to loud sound) — word knowledge depends on hearing, so a hearing check is part of any escalation.
When to escalate
Refer to the Medical Officer or nearest developmental/early-intervention service at the first clear flag — do not adopt wait-and-watch beyond a single short review. A red flag plus parental concern is enough to act. Document what the child does, not only what they don't, and pass on the parent's own observations — they are valuable clinical information.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist. Our team builds a full picture of a child's word knowledge and hearing, and our speech therapy clinicians shape playful, family-led support around it.Trusted sources

Refer the family to book a developmental assessment with a Pinnacle clinician for a calm, clear review.
What to watch
Escalate if: no babbling or gestures by 12 months; no single words by 18 months; fewer than ~50 words or no two-word phrases by 24 months; doesn't follow a one-step instruction; doesn't respond to name or point; or has lost words once used. Add a hearing check, and act on a red flag plus parental concern.
Try this at home
During home visits, ask the parent to list the words the child uses and to show one simple instruction the child follows. A short note of what the child does — not only what they don't — gives the Medical Officer a clear picture.

Frequently asked
At what age should a child say their first words?
Most children say a few single words by around 12 months and many more by 18 months. If there are no single words by 18 months, it's worth a developmental check — not as a diagnosis, but to catch anything early.
Should I wait and watch before referring?
A red flag together with a worried parent is enough to refer now. Beyond a single short review, prolonged wait-and-watch is not advised — early support works best, and a clinician can reassure if all is well.
Could a hearing problem be the cause?
Yes. Word knowledge depends on hearing, so frequent ear infections or no startle to loud sounds matter. A hearing check should be part of any escalation for delayed words.
