If the interrogative word is subject or a modifier of it, the order is usual.
+Examples+.—Who came last evening? What star shines brightest?
+Direction+.—Write five interrogative sentences, using the first word below as a subject; the second as a subject and then as a modifier of the subject; the third as a subject and then as a modifier of the subject:—
Who, which, what.
If the interrogative word is object complement or attribute complement or a modifier of either, the order is transposed.
+Examples+.—Whom did you see? What are personal consequences? Which course will you choose?
+Direction+.—Write an interrogative sentence with the first word below as object complement, and another with the second word as attribute complement. Write four with the third and the fourth as complements, and four with the third and the fourth as modifiers of the complement:—
Whom, who, which, what.
If the interrogative word is an adverb, the order is transposed.
+Examples+.—Why is the forum crowded? Where are the flowers, the fair young flowers?
