Codenames for ESL Classes: A Teacher’s Guide

Ask an experienced ESL teacher for one game that earns its forty minutes and a surprising number will say Codenames. Not because it teaches vocabulary — it barely does — but because it forces the single hardest skill in a second language: describing something when you do not have the word for it.

Why it works on language learners

A spymaster has to make a teammate think of CROWN using one word that is not CROWN. That is circumlocution, and it is the difference between a learner who stalls mid-sentence and one who talks their way around the gap and keeps going. Textbooks almost never drill it. A single round of this game drills it twenty times.

Two more things happen that teachers tend to notice by the second round. The guessers argue — in English, unprompted, because the game gives them something worth arguing about. And the quiet students speak, because a wrong guess is the game working rather than a personal failure.

Adapting it by level

• A2. Shrink the grid to 4×4 and pre-teach the board. Allow two-word clues. Allow a gesture. The aim is sentences, not difficulty.
• B1. Standard grid, one-word clues, but let the spymaster pass without penalty. Ban proper nouns so nobody wins on trivia.
• B2. Add a one-minute clue timer. Time pressure is where fluency actually lives.
• C1. Require the spymaster to justify the clue afterwards, in English, to the other team. That short explanation is the most valuable minute of the lesson.

Running it in a class

Split into two teams and rotate the spymaster every round, so no confident student owns the role for the whole lesson. Keep a scrap of board space for words the class did not know — they come up naturally, which is the only way vocabulary ever sticks. And resist correcting mid-round. Note the errors, play the round out, and go through three of them at the end; interrupting a game to fix a preposition teaches students that speaking invites correction, which is precisely the reflex you are trying to remove.

If your class is online or on phones

The physical game needs everyone around one table looking at one grid, which is awkward on a video call and impossible with a split class. Word Spies on TalkSibi is our own take on the one-word-clue format, built for learners: everyone joins from their own phone or laptop with a code, spymasters see their own view, and nobody has to hold a camera over a board.

It also sits next to the thing a class cannot provide — actual native speakers to practise with afterwards. If you teach adults, that combination is worth showing them once.

A word of warning

The game rewards cultural knowledge more than teachers expect. A clue like THANKSGIVING or CRICKET lands very differently depending on where your students grew up. Ban the category rather than the word when it comes up, and it stops being a problem.
