What for Who, Which, and That.—See [Relative Pronouns].
Where for In which.—“It is a cause where justice is particularly concerned.” Say in which. “We presented a paper where his case was fully explained.” Say “a paper in which.” But where may be used instead of which and a preposition when place is the predominant idea. “The old house where I was born.”
Whether is followed by or. “Whether he will go or not, I cannot tell.”
Which.—See [Relative Pronouns].
Who.—See [Relative Pronouns].
Without, Unless.—Without must not be used for unless. “You won’t catch the train without you run,” should be, “You won’t catch the train unless you run.”
“My uncle would not take me without my mother wished it,” should be “My uncle would not take me unless my mother wished it.”
Wrong and Wrongly.—Wrong is an adverb as well as an adjective. For this reason, wrong is often interchangeably used with wrongly; as, “The mail was sent off wrong” (or wrongly). When preceding the verb, wrongly is required; as “The letter was wrongly addressed.”
