where you can put things on

[Will17]

Hello,

Is "on" necessary at the end of this sentence, please?

"A shelf is a horizontal board where you can put things on".

Thanks a lot for your help.

No.

I'd go further and say that "on" is wrong there. You could say "to put things on" or, less likely in modern English "on which to put things".

Hello Will17,

In your case, 'on' is used to refer to a flat surface.

A tabletop is a horizontal board to put things on.
A coffee table is a horizontal board to put things on.
A shelf is a horizontal board to put things on.

A jewelry case is a box to put things IN.


Personally, I would not say you are wrong but whether it is necessary depends on how specific and descriptive you want your definition to be.

A shelf is a board.
A shelf is a horizontal board.
A shelf is a horizontal board you can put things on.
A shelf is a horizontal board you can put books, toys and food on.

Hope that's clear :)
