"I buy a clock with money."

As opposed to buying it with beer and hand...shakes.

Ha.

Right

[Yugenli]

Why is a "de" used?

[Shinobusagi]

で indicates something you use, and so is often translated as "with" or "by". E.g. 筆で書きます　（ふででかきます）　"I write with a brush", or 電車で来ました　（でんしゃできました） "I came by train".

[Japanarchist]

Do you happen to go by 'Onestitchatatime' elswhere on the internet?

[Shinobusagi]

No, elsewhere on the internet I mostly go by 'Trochilus'.

[kokaku]

is there an order to particle use? could Xを Yで be used?

[T33K3SS3LCH3N]

You generally have quite some freedom with how to order noun/particle combinations. Switching order should be no problem here.

[Mawticus]

I answered in that order and it was marked correct. However, i can see further down the comments, user Trissie suggests that order is important in this case. Google translate backs that up; I plugged in とけいをお金でかいます and got "I will charge money by watching".

[Xyvyrianeth]

金 (きん) means "gold"

お金 (おかね) means "money"

[koichi81957]

The english is more natural if "I will buy a clock with money"
