This is my first post here so I apologise in advance for any irrelevancies.
I am posting because I wonder if I can put down a sentence like ''they have enriched their functions by embracing technological innovations...''. What I try to convey is that ''they have diversified their functions'' and ''made their contents of their functions more rich''.
I am asking because my supervisor said that functions can only be ''enhanced'' rather than ''enriched.'' So I'm afraid of misusing the word or making this sentence weird. Could you guys give me some hints about that? Any feedback, even as simple as a ''yes'' or a ''no,'' would all be greatly appreciated.
