, "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.

OBS. 11.--Of the infinitive verb and its preposition _to_, some grammarians
say, that they must never be separated by an adverb. It is true, that the
adverb is, in general, more elegantly placed before the preposition than
after it; but, possibly, the latter position of it may sometimes contribute
to perspicuity, which is more essential than elegance: as, "If any man
refuse _so to implore_, and _to so receive_ pardon, let him die the
death."--_Fuller, on the Gospel_, p. 209. The latter word _so_, if placed
like the former, might possibly be understood in a different sense from
what it now bears. But perhaps it would be better to say. "If any man
refuse so to implore, and _on such terms_ to receive pardon, let him die
the death." "Honour teaches us _properly_ to respect ourselves."--_Murray's
Key_, ii, 252. Here it is not quite clear, to which verb the adverb
"_properly_" relates. Some change of the expression is therefore needful.
The right to place an adverb sometimes between _to_ and its verb, should, I
think, be conceded to the poets: as,

"Who dared _to nobly stem_ tyrannic pride."--BURNS: _C. Sat. N._

OBS. 12.--The adverb _no_ is used independently, only when it is equivalent
to a whole sentence. This word is sometimes an adverb of _degree_; and as
such it has this peculiarity, that it can relate only to comparatives: as,
"_No_ mor
