If I applied minor changes to a sentence, e.g. substituted two words in a ten-word one, or added a phrase halfway through, what would the verb which describes this action be?
My first thought was "rephrase" or "paraphrase" but neither seems to work since, as far as I can tell, they both indicate applying major changes which is not exactly what I am looking for.
Then I wondered if "reword" could be the verb but, again, does not seem to carry the intended meaning.
The context is: a saying that has been altered in a way which made it flexible and able to be used freely without sticking to the original structure.
