SPEECH AND LANGUAGE

Words are not increasing:
how vocabulary actually grows

Parents often try to teach words. Children rarely learn them that way. They learn a word when an adult names what they are already looking at, at the moment they are looking at it, many times, and the word works. Once you see that, the way forward at home becomes obvious — and so does the one sign that should not be waited out.

How a word lands

Three conditions, every time: the child's attention is on the thing; the word meets them there, repeatedly; and the child gets the feeling that it worked — they said (or tried) something and the world responded. Vocabulary grows in life and play, not in lessons.

Three things to do at home

  • Narrate, like a commentator. Put words on what your child is doing and looking at, as it happens — in whichever of your languages comes naturally.
  • Start from what they love. Trains, dogs, bubbles: the words around a passion land first and spread outward.
  • Accept the imperfect, return the correct form. "Ba!" — "yes, a ball!" No correction, no repetition demanded; just the model, warmly.

Why flashcards underperform

Cards are not bad; they are just not where words land. A word met on a card once is weaker than a word met fifty times in the bath, at the park and in a book. Life and play, with an adult who names things, is the method.

Ask sooner if…

  • Months after the first words, your child still has only a handful — in all languages combined
  • Words your child used to say have disappeared — this is the one sign not to wait out; talk to a professional early
  • You have concerns about understanding, not only speaking
  • Any concern about hearing

Start with your ward's public health centre or child development support centre, or come and see us. No diagnosis is needed to talk.

How many words is "enough"?

There is no single safe number. We look at the whole picture: how much your child understands, how they interact — pointing, sharing, turn-taking — and whether the number is growing. For bilingual children, count across all languages. If you are unsure, bring the printable checklist to a visit and we will look at it together.

This page is general information for families, based on the Japanese pages of our classroom and the public sources listed above. It is not medical advice and does not replace an assessment by a doctor or other specialist. Whether your child needs support, and which class your child enters at school, are decided with you by the relevant professionals and your ward — not by this page.

FAQ

Questions families ask

Should we use only one language so words come faster?
The speech-language profession's position is that two languages do not cause delay. A strong home language supports the child; keep speaking it.
Our child understands everything but says little. Is that OK?
Good understanding is a very good sign. Watch the trend over a few months and look at interaction (pointing, sharing). If words are not starting to come, ask.
Are apps and videos useful for vocabulary?
Far less than a person who names things in the moment. A screen does not respond to where your child is looking or to what they try to say.
