Clean Language

Clean Language is a precise questioning technique developed by therapist David Grove in the 1980s. Facilitators use a small set of carefully worded, non-interpretive questions — such as 'And when X, what happens next?' — to help participants surface and examine their own metaphors and implicit assumptions. It is ideal for deep coaching conversations, conflict resolution, and uncovering the true nature of complex problems without contaminating responses with the facilitator's own worldview.

How to run it

  1. 1

    Brief participants on the purpose: the facilitator's role is to illuminate the participant's own thinking, not to interpret or lead.

  2. 2

    Start with an open question to invite a topic: 'What would you like to have happen?' or 'What's important to you about this challenge?'

  3. 3

    Listen carefully for the participant's exact words and any metaphors they use (e.g., 'I feel stuck in a corner').

  4. 4

    Respond using only Clean Language questions, staying strictly within the participant's own vocabulary: 'And when you're stuck in a corner, what kind of corner is that corner?' or 'And what happens just before you feel stuck?'

  5. 5

    Continue exploring the metaphoric landscape with questions such as: 'And where is X?', 'And what's X like?', 'And when X, what happens to Y?', 'And what would you like to have happen?'

  6. 6

    Allow the participant to arrive at their own insights and reframings — resist the urge to offer solutions, interpretations, or advice.

  7. 7

    Close by asking the participant to summarise what they have discovered and what, if anything, they want to do differently.

Tips

  • The key discipline is resisting the impulse to paraphrase or interpret.

  • Use the participant's exact words, even if they sound unusual.

  • Practice the core questions until they feel natural — beginners often find a laminated prompt card helpful.

  • In group settings, pairs work better than triads so everyone gets significant speaking time.

Variations

Group Clean Language: one facilitator works with a small group, asking clean questions publicly so everyone can observe and learn the process simultaneously. Can be combined with Systemic Modelling for team-level work. In coaching circles, participants take turns as questioner and explorer.
