Are you counting on tools on your computer to identify errors in your document? Spell check and grammar check have limited uses. There are certain errors that they just cannot pick up; I see this happen all the time.
Semantic errors are not things your computer can fix for you.
For example, “discrete” and “discreet” are both proper English words but not used in the same way. Spell check won’t help you there.
It is wrong to say “I asked her severally” when you mean “I asked her several times” but your computer can’t tell you, because “severally” is also a word- used differently.
Don’t risk turning your readers off. Ensure that your work is memorable for all the right reasons. I’m at your service! #YouNeedAnEditor
