Do you use both prepositions?

teacherJapanAn elderly woman fell off/from the platform.

No, not usually.

Thank you:)

Your question is ambiguous. Do you mean the alternative usage, i.e. off vs from, or off/from vs 'off from'?

Ah, you are right!! Sorry for the confusion!
I meant to ask whether the following expressions are both possible.

1) fall from the platform
2) fall off the platform

Yes, they're both certainly possible and in use. My first comment is that I don't use both. I suspect that most speakers have an unconscious preference.

Ah, it's a matter of preference:) That's a relief:). I am sorry to have confused you with my first question. Thank you very much
