I know that putting words in square brackets when quoting is used to clarify or emphasize something, but I've seen some cases where it really doesn't make sense to me.
For example this sentence:
If you drink a liter of water, [urination] will increase
from this context:
He added that any increase in fluid input will lead to an increase in urine output. "If you drink a liter of water, [urination] will increase," Armstrong said. "Doesn't mean you shouldn't drink water."
So, the word in brackets is added by the writer of the article, but hasn't been said by the quoted person, right? What boggles me is why would the writer put
urination in brackets, when the sentence would obviously not make sense, if we omit that specific word in this specific case...?
If you drink a liter of water, will increase
doesn't really sound right to me.
