"Step on scale, please" represents which function of the language?

Answer: Directive

• Reason: The utterance asks the listener to perform a specific action. The imperative form "Step on scale" functions as an instruction or request.

• Politeness marker: The word "please" makes the instruction a polite request, which is typical of directive language.

• Why other functions do not fit:

  • Informative: Presents facts or information; this utterance does not describe or report anything.

  • Expressive: Conveys emotions or attitudes; this utterance does not express the speaker's feelings.

  • Performative: Performs an action by being spoken (for example, making a declaration). This utterance requests action from the listener rather than performing an act itself.
