This question already has an answer here:
I frequently find this expression in literature and such. I couldn´t find anything on it on the net, only more of these expressions without explanations how to handle or understand them correctly:
"I have years of experience proofreading, editing and translating. From simple CVs and cover letters to Master Theses, it is important that your work be perfect and I will make sure that your end product is error-free."
Is that actually idiomatic language? Can it be replaced by "is"?
