whole phrase is used as an interjection, and we call such interjectional phrases:  as, out upon him!—­away with him!—­Alas, what wonder! &c.”—­Conversations on Gram., p. 79.  This method of lumping together several different parts of speech under the notion of one, and calling the whole an “adverbial phrase,” a “substantive phrase,” or an “interjectional phrase,” is but a forced put, by which some grammarians would dodge certain difficulties which they know not how to meet.  It is directly repugnant to the idea of parsing; for the parser ever deals with the parts of speech as such, and not with whole phrases in the lump.  The foregoing adverbs when used imperatively, have some resemblance to interjections; but, in some of the examples above cited, they certainly are not used in this manner.

OBS. 9.—­A conjunctive adverb usually relates to two verbs at the same time, and thus connects two clauses of a compound sentence; as, “And the rest will I set in order when I come,”—­1 Cor., xi, 34.  Here when is a conjunctive adverb of time, and relates to the two verbs will set and come; the meaning being, “And the rest will I set in order at the time at which I come.”  This adverb when is often used erroneously in lieu of a nominative after is, to which construction of the word, such an interpretation as the foregoing would not be applicable; because the person means to tell, not when, but what, the thing is, of which he speaks:  as, “Another cause of obscurity is when the structure of the sentence is too much complicated, or too artificial; or when the sense is too long suspended by parentheses.”—­Campbell’s Rhet., p. 246.  Here the conjunction that would be much better than when, but the sentence might advantageously spare them both; thus, “An other cause of obscurity is too much complication, too artificial a structure of the sentence, or too long a suspension of the sense by parenthesis.”

OBS. 10.—­For the placing of adverbs, no definite general rule can be given; yet is there no other part of speech so liable to be misplaced.  Those which relate to adjectives, or to other adverbs, with very few exceptions, immediately precede them; and those which belong to compound verbs, are commonly placed after the first auxiliary; or, if they be emphatical, after the whole verb.  Those which relate to simple verbs, or to simple participles, are placed sometimes before and sometimes after them.  Examples are so very common, I shall cite but one:  “A man may, in respect to grammatical purity, speak unexceptionably, and yet speak obscurely, or ambiguously; and though we cannot say, that a man may speak properly, and at the same time speak unintelligibly, yet this last case falls more naturally to be considered as an offence against perspicuity, than as a violation of propriety.”—­Campbell’s Rhet., p. 239.
