Is "since" necessary in the sentence? "Never speak harsh words, since once spoken they may return to you." [closed]
I got this sentence from my English class. Some said 'since' can be omitted.
Solution 1:
Since in this sentence is a conjunction; both parts of your sentence are complete sentences by themselves, so you need a conjunction word (or a semicolon) to join them together. Without since, this becomes a run-on sentence.
