To parse an adverb is to state the kind of adverb, its =degree= of
comparison, if it has any, and what it =modifies=.
=Model.=—_Now_ you may read it.
_Now_, an adverb of time, modifying the verb-phrase _may read_.
=Model.=—I know _where_ you put it.
_Where_, a conjunctive adverb, showing place. It modifies _put_ and
connects the clause, [_where_] _you put it_ with the clause, _I know_.
