Function versus grammatical form

Cambridge Veritas · Original TESOL self-study resources

Understand the idea

A grammatical structure can perform several functions. A question may request an action; a statement may warn or invite. Learners need to interpret speaker purpose as well as identify sentence structure.

What you will practise

• Explain the key idea in “Function versus grammatical form” using a concrete example.
• Choose a teaching response that fits the learner and the purpose.
• Identify evidence you could collect to evaluate that response.

A closer look at the teaching

Ask what response would show understanding of the speaker’s intention. If a request receives only a literal ability answer, the grammar may have been understood while the function was missed. Compare complete exchanges and let learners judge whether the response fits. This links language awareness to interaction rather than a classification exercise alone.

Functional language connects linguistic choices with what people are trying to achieve together. Learners need to recognise intentions, choose an expression that fits the relationship and respond appropriately to the next turn. A list of request or suggestion phrases is therefore only part of the lesson. Establish a scene, compare a short exchange and provide an opportunity to reach a real decision or solve a communicative problem.

In the classroom

Before choosing an activity, identify what the learner needs to understand or communicate. Separate the language demand from other demands such as reading instructions, managing equipment or speaking to a large group.

A teaching sequence you can adapt

Use these stages as a starting point for this topic. Keep the language goal visible, and change the support when learner responses show a different need.

1. 01

   Create a recognisable scene and state what the participants need to achieve.

2. 02

   Read or hear a short model exchange, checking the overall outcome before analysing useful phrases.

3. 03

   Compare choices of wording and delivery, then rehearse a small set of responses with support.

4. 04

   Change the situation or information and ask learners to achieve the outcome, followed by feedback on success and appropriacy.

A common mistake to avoid

When reviewing the activity, distinguish what you observed from what you inferred. Use the task outcome and a fresh example to decide whether another explanation, a different scaffold or more independent practice is needed.

Adapt it for your learners

Keep the intended outcome consistent when comparing responses. Record which support was available so you do not confuse a supported performance with the same task completed independently.

Try it, then compare.

Take a moment to make your own decision. Compare your reasoning with the example, then adapt it for a teaching context you know.

Your questions, answered.

Quick revision

• The key idea: A grammatical structure can perform several functions.
• The context to remember: “There’s someone at the door” is said to a person sitting near the entrance.
• A useful next step: Suggest two possible functions in different contexts.

For your teaching portfolio: keep a brief plan, a note of what learners actually did and one change you would make next time. Use anonymous examples.
