CHAPTER VI
INDEPENDENT ELEMENTS
+501.+ +A word or group of words that has no grammatical connection with the sentence in which it stands is called an independent element.+
+Independent elements are of four kinds,--interjections, vocatives (or nominatives by direct address), exclamatory nominatives, and parenthetical expressions.+
_Ah!_ why did I undertake this task?
Help arrived, _alas!_ too late.
You are a strange man, _Arthur_.
_Mary_, come here!
Poor _Charles_! I am sorry for him.
_Clothes! clothes!_ you are always wanting clothes.
Lucky _she_! we are all envious of her prospects.
The first two sentences contain +interjections+ (§ 372); the second two, +vocatives+ (or nominatives by direct address) (§ 88, 3); the last three, +exclamatory nominatives+ (§ 88, 4).
When the independent word has a +modifier+ (as in the fifth and seventh examples), the whole phrase may be treated as an independent element.
+502.+ +A word or group of words attached to or inserted in a sentence as a mere comment, without belonging either to the subject or the predicate, is said to be parenthetical.+
The market, _indeed_, was already closed.
Peter, _to be sure_, was not very trustworthy.
The house, _at all events_, is safe.
The road is, _I admit_, very hilly.
Luttrell’s method, _it must be confessed_, was a little disappointing.
Richard was not a bad fellow, _after all_.
+503.+ In analysis, an independent element is mentioned by itself, and not as a part of the complete subject or the complete predicate.
