Random Word Generator — ESL Vocabulary Tool

One button. One word. Infinite possibilities. The Random Word Generator pulls a vocabulary word at random from the ESLe College database and displays it clearly on screen — ready for whatever activity you have in mind. One of the tools in the ESLe Teacher Hub, it is the simplest tool in the collection and arguably the most versatile.

How to use it

Set your level and topic filters, press Generate and a vocabulary word appears. Press again for a new word. Every word comes with its part of speech and a usage example — useful context when the word is unfamiliar or when you want to show students how it functions in a sentence.

• Filter by CEFR level — A1 through C1 — to match your students' exam
• Filter by topic to focus on your current unit
• Part of speech and example sentence displayed with each word
• Large clear display designed for classroom projection
• Press again instantly for a new word — no loading, no delay

A hundred uses in a single lesson

The Random Word Generator is deliberately minimal because the activity is whatever you make it. Generate a word and ask students to give a definition in their own words — no dictionaries, just thinking. Generate a word and ask for a synonym, an antonym, or a collocation. Ask students to use the word in a spoken sentence with a specific tense. Generate three words and ask students to write a short paragraph using all three. Give students 60 seconds to draw the word on mini whiteboards while the class guesses. Use it as a discussion prompt — generate an abstract noun and debate it.

For IB English B classes, filter to a specific theme and use the random word as the starting point for a paper-style spoken interaction. For IGCSE ESL and Cambridge B2 First students, focus on B1 and B2 level words and practise paraphrasing — a skill tested directly in the speaking and reading components of those exams.

For teachers

Keep the Random Word Generator open in a tab throughout your lesson as a go-to filler activity. It takes no preparation and generates genuine spontaneous language from students — which is often more valuable than any scripted activity. Pair it with the Class Timer for a timed production challenge, or try Spin the Wheel for the same idea in a more theatrical format. The full Teacher Hub has all available classroom tools.
