Proposition should not be confounded with proposal. A proposition is a statement of a statement or a plan. A proposal is the presentation or statement of an offer.
Providing should not be used for provided.
Quality should never be used as an adjective or with an adjective sense. "Quality clothes" is meaningless: "Clothes of quality" equally so. All clothes have quality and the expression has meaning only when the quality is defined as good, bad, high, low, and so forth.
Quit, "to go away from" is not the same as stop.
Quite means "entirely," "wholly," and should never be used in the modifying sense as if meaning rather or somewhat. "Quite a few" is nonsense.
Raise is a much abused word. It is never a noun. As a verb it should be distinguished from rear and increase, as in such phrases as "He was raised in Texas." "The landlord raised my rent."
Rarely ever should not be used for rarely or hardly ever.
Real should not be used in the sense of very.
Reference should be used with with rather than in. Say with reference to, not in reference to. The same rule applies to the words regard and respect. Do not say "in regards to," say "with regard to."
Remember is not the same as recollect, which means "to remember by an effort."
