Can we use "likewise" instead of "also" in formal writing?
Solution 1:
You can certainly use "likewise" anywhere it fits and there is no reason why you can't also use the word "also" in an academic paper. I personally tend to use "also" only when necessary but sure, you can do it.
also (adverb)
- in addition
- in a similar way
likewise (adverb)
- in the same way
- in addition
They aren't exactly synonymous but they can often be used in the same places.
