Aim or purpose?

[splash_jony]

Hi everyone

I got a sentence like this :
The aim of research is to find the new food source.

Can I change the aim to purpose?
Is there any difference between them?

You can certainly substitute "purpose" for "aim" in that sentence. If you look the two words up (perhaps in WR's dictionary), you will see that there are some definitions for "aim" that are not listed for "purpose". So "aim" and "purpose" are not always synonyms. In your sentence, they are synonyms.
