Buy to or from

[Will17]

Hello!

Is the use of "from" correct in this sentence, please?

"That big millionaire bought the patent from an engineer".

Could we use "to" instead without changing the meaning?

Thanks a lot

I am not a teacher.

No, you can not interchange "from" and "to" without changing meaning. In this case, "to" would not make sense at all.

To and from are essentially antonyms.

'...buy from' '...sell to.'
