Why Memorising Vocabulary Does Not Always Lead to Speaking

A learner studies a list of ten words on Sunday, gets all ten right in Tuesday’s test and then, on Friday, describes a rainy day as “very bad weather” even though “gloomy” was on the list.

Nothing went wrong with the memorising. The learner learned the word for one kind of task, matching or spelling it, and that knowledge does not automatically carry over to another kind of task, choosing it in a sentence.

Knowing a word has layers

Knowing a word is not a single yes or no. A learner may:

• recognise it when they see it
• understand it when they hear it in a sentence
• remember its meaning when someone asks
• produce it when they need it, without a prompt
• use it with the words it usually goes with, like heavy rain rather than strong rain

Vocabulary lists usually train the first three. Speaking needs the last two.

Why retrieval is the part that needs practice

What tends to help

• Fewer words, used more often. Five words used in sentences across a week often do more than twenty words copied once.
• Ask for the word, not the meaning. “What’s a word for a day that is dark and a bit sad?” practises retrieval. “What does gloomy mean?” practises recognition.
• Pair the word with its usual partners. Teach make a mistake, heavy rain, take a photo as chunks, so the learner has ready-made phrases.
• Come back to it later. Bring a word back two days later, then a week later, in a new context.
• Let the learner use it about their own life. “Tell me about a gloomy day you remember” connects the word to something real.
