Hi,

1. Why does it have to be 'prior to the main narrative time frame' here? Can it be 'past the main narrative time frame'?

The future perfect progressive verb will have been listening suggests action that will begin in the time frame prior to the main narrative time frame and that will be still be underway when another action begins.

2. Is this use of present perfect OK as part of what looks like instructions or a definition?

An electrical instrument that is heated and used to sooth clothes after you have dried them.

Consider this timeline for tomorrow.

6pm. I will start cooking dinner.

7pm I will finish cooking dinner.

If you call me at 6.60 pm tomorrow, I will have been cooking dinner for half an hour.

I don't understand your question, Can it be 'past the main narrative time frame'? Can you please provide a timeline similar to the above, to show what you are asking about?

2. Is this use of present perfect OK as part of what looks like instructions or a definition?

An electrical instrument that is heated and used to sooth clothes after you have dried them.

Yes. But the passive is often used in such a context to avoid the use of 'you', ie to avoid any reference to an agent.

An electrical instrument that is heated and used to sooth iron clothes after they have been dried.

Hi, Clive.

I think there is no need for a timeline like the one you had because your explanation with the timelime has already answered my question. Thank you.
