關於Triple的意思和用法的提問

A: It is just short for "at three times"

A: "He committed triple murder."
"The copper energy cells had triple the efficiency of silicon cells."
"Sales are expected to triple."

A: As a native speaker, I did not know this, but originally they meant the same thing.

"Treble" is obsolete/out of use in any sense other than "high pitched", which comes from it being used to talk about the highest part in a musical trio (so it literally meant the "triple" part.)

I learned something new today by looking up the etymology in order to answer this question.

A: Triple means in threes
Triple chocolate cookies have three types of chocolate
Treble means it has three parts, or happens three times, like 000 would be treble zero

Some people use them in place of each other, which is non-standard, but still understandable.

A: treble refers to music, like the treble clef (G clef)

A: Grazie mille ❤️
