One-word answers are common at this age and are usually not an inability but a habit or a lack of confidence. The way to encourage longer speaking is to ask open-ended questions that can't be brushed off with "yes/no," give them time to think, and create opportunities to produce the language. As production increases, fluency develops too.
Detailed Explanation
One-word answers often worry parents; but they usually carry good news: if the child is answering, they understand. What's missing is not knowledge but the habit of producing the language at greater length and with more courage.
Why one word?
There can be several reasons: the child may prefer to give the answer with the least effort, may lack confidence to speak at length, or the question may simply be one that can be answered in a word. Applied linguist Merrill Swain's "output" approach emphasizes that an important part of learning a language is producing it: the more and the longer a child speaks, the more they consolidate the language. So the goal is to gently increase production.
Open-ended questions and thinking time
The most practical way to increase production is to change the form of questions. "Did you like this?" is answered in a word (yes/no); but open-ended questions like "why did you like this?" or "what do you think happens next?" invite the child to form a sentence. It's also important to give the child thinking time: silence is often the moment a child needs to build the sentence.
To encourage longer speaking
- Ask open-ended questions ("why," "how," "what do you think"); avoid yes/no questions.
- Give the child thinking time; don't rush the answer.
- Use gentle expansion prompts like "and tell me why you think so."
- Let the child talk about topics that interest them; interest lengthens speech.
- Instead of correcting the one word, model a full-sentence answer yourself.
Points to keep in mind
Insisting "make a full sentence!" usually overwhelms the child and pushes them away from speaking altogether. Also, not every one-word answer is a problem; short answers are given in real life too. The goal is not to push the child but to make longer speaking appealing and safe. Fluency develops through plentiful, enjoyable production, not pressure.
Expert Note — Sarah Emam
I never tell a child who gives one-word answers to "make a full sentence"; instead, I curiously ask one more question. "Why?" is a magic word; it invites the child to form a sentence without realizing it. Conversation lengthens with someone who asks the right questions, not someone who pushes the child.
