Raising-to-subject verbs vs. auxiliary verbs
The raising-to-subject verbs
seem and
appear are similar to auxiliary verbs insofar as both verb types have little to no semantic content. The content that they do have is functional in nature. In this area, auxiliary verbs cannot be viewed as separate predicates; they are, rather, part of a predicate. The raising-to-subject verbs
seem and
appear are similar insofar it is difficult to view them as predicates. They serve, rather, to modify a predicate. That this is so can be seen in the fact that the following pairs of sentences are essentially synonymous: ::a. Fred does
not seem to have done it. ::b. Fred seems
not to have done it. – Position of the negation is flexible. ::c. Fred seems to
not have done it. – Infinitival splitting occurs. ::a. Mary does
not appear to like pudding. ::b. Mary appears
not to like pudding. – Position of the negation is flexible. ::c. Mary appears to
not like pudding. – Infinitival splitting occurs. The fact that position of the negation can change without influencing the meaning is telling. It means that the raising-to-subject verbs can hardly be viewed as predicates. While raising-to-subject verbs are like auxiliary verbs insofar as they lack the content of predicates, they are unlike auxiliaries in syntactic respects. Auxiliary verbs undergo subject-aux inversion, raising-to-subject verbs do not. Auxiliary verbs license negation, raising-to-subject verbs do so only reluctantly: ::a. Fred
is happy. ::b.
Is Fred happy? – Auxiliary verb
be takes part in
subject-auxiliary inversion. ::c. Fred is
not happy. – Auxiliary verb
be licenses negation. ::a. Fred
seems happy. ::b. *
Seems Fred happy? – Raising-to-subject verb
seem cannot take part in subject-auxiliary inversion. ::c.
??Fred seems
not happy. – Raising-to-subject verb
seem can hardly license negation. ::a. Susan
should stay. ::b.
Should Susan stay? – Modal auxiliary
should takes part in subject-auxiliary inversion. ::c. Susan should
not stay. – Modal auxiliary
should can license negation. ::a. Susan
appears to be staying. ::b. *
Appears Susan to be staying? – Raising-to-subject verb
appear cannot take part in subject-auxiliary inversion. ::c.
?Susan appears
not to be staying. – Raising-to-subject verb
appear reluctantly licenses negation. Raising-to-object verbs are also clearly NOT auxiliary verbs. Unlike raising-to-subject verbs, however, raising-to-object verbs have clear semantic content, so they are hence indisputably predicates. ==Representing raising==
