Children vary widely; steady growth matters more than an exact count. A friendly developmental screen helps if understanding or finding words seems persistently behind.","answer_md":"*Words don't arrive on a timetable, but their growth follows a path you can gently watch.*\n\n## In short\n\"Word knowledge\" means the bank of words a child understands and uses — what they mean, how they connect. Between **3 and 7 years** this grows beautifully fast: from around 200–1,000 words at age 3 to several thousand by age 5, with richer meanings and categories (animals, colours, feelings) layering in through to age 7. Children vary widely, and steady growth matters far more than hitting an exact number on an exact day.\n\n## What healthy word knowledge looks like\n- **By 3 years** — uses hundreds of words, names familiar people, objects and a few actions; follows simple two-step requests.\n- **By 4 years** — asks lots of \"why\" and \"what\" questions, groups words (\"fruits\", \"animals\"), uses words for time and feelings.\n- **By 5 years** — understands opposites, position words (under, behind) and several thousand words; tells a short story in order.\n- **By 6–7 years** — defines words, understands that one word can have two meanings, learns new words from reading and conversation.\n\n## The science\nWord knowledge (ICF **d3**, communication) grows through everyday talk, shared books and play — not drills. Children learn words best when adults name what the child is already looking at and gently expand on it. Persistent difficulty understanding or finding words, beyond the usual range, is worth a friendly developmental check rather than a wait.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a website or a worry.
