I wrote the following sentence:

On the other hand, there would be many downsides of communicating in just one language globally.

Grammarly premium in academic mod suggested re-writing it as:

On the other hand, there would be many downsides to communicating in just one language globally.

Then I checked dictionaries and found these sentences:

The downside of living here, of course, is that it is expensive. (https://dictionary.cambridge.org/dictionary/english/downside)

The downside of all this success is that I don't get to spend much time with my family.(https://www.oxfordlearnersdictionaries.com/definition/english/downside?q=downside)

After looking the dictionaries up I thought that what Grammarly suggest is wrong.

Is it 'downside of something' or 'downside to something'?

    Either is fine.

    Both prepositions are fine, and the mean exactly the same. Americans use both about equally often, but Brits have a significant preference for "the downside to..." But we're not here to "debug" Grammarly. Jan 17, 2023 at 18:32
  • Either is fine. But I don't like downsideS. I would write it so there is only one downside, and make it emphatic somehow. Maybe multi-faceted, or large, or intense in some way.

  • I think 'downside' is still a little informal, at least in British English. Jan 17, 2023 at 23:01

I think it's a matter of stylistic choice. Some speakers might even argue that "downside in" is also fine.

For what it's worth, "downside to" sounds best to me in your example but I don't know why.


Prepositions are often interchangeable in English.

It is common to say there is a downside "to" doing something. However, it is not incorrect to say there is a downside "with" something, or a downside "of" a thing.

When we refer to "sides" of something, we often use "of" (the outside of a thing, the right side of a thing, etc.). So it is that in some phrases, "downside" goes with "of". For example, "The downside of working from home is the lack of face-to-face contact with colleagues."

As to the original question, I do think "...downside to communicating..." sounds better than "...downside of communicating..." But it is a subtle difference and "of" is understandable.
