CONTENT
Syntax is autonomous!
Many people disagreed
No real evidence!
Nobody believes it, anyway!
Unification Grammars
Content is important
Meaning and grammar work together
CONTENT is unified through the head
V onto VP and so on
Notice the structure-sharing
[sees us] – what about the SEER?
The squared numbers …
… a shortcut to show structure-sharing
[he sees us]
Notice the CONT shared up the head
V to VP to VP
Look at CONT
Structure-sharing is dynamic
It looks like it’s MOVING up the tree
The ILLUSION of movement
Shut up! It’s REALLY movement!!
No, maybe it’s just an ILLUSION
Think about [seems]
[Taro seems to like Hanako]
[Taro] is the grammatical subject
But also the logical subject of [like]
[Taro] is the LIKER
He’s not a SEEMER!
So what’s happening? Is it movement?
Maybe not
Look at the VALENCE features SUBJ
and COMPS
[seems] takes a normal subject
And a complement …
The complement is a infinitival VP
The subject [1] of the inf VP …
… is structure-shared with the normal
subject [1]
And the CONT of the inf VP
Is structure-shared in the CONT of
[seems]
Appearance that Taro likes Hanko
Looks OK
Now look at [to like Hanako]
Subject is empty
CONT is passed up the tree
[seems to like Hanako]
Subject of [seems] unifies with the
subject of inf VP
CONT of the subject unifies in CONT of
[like]
Full sentence
Taro seems to like Hanako
CONT of [Taro] unifies through the
whole structure
Gives the meaning without movement
How about this?
[tries to impress Hanako]
[try] and [seem] are different
[seem to impress] – there’s no SEEMER
[try to impress] – there is a TRYER
You’re TRYING to do something
CONT of [try] is different
There’s a TRYER
[seem] there’s no SEEMER
[seem] No SEEMER
That is really simple
And rather natural
But Transformational Grammars can’t
do it
Because meaning and grammar are
separate
Transformational Grammars are
limited

Unification grammars have syntax and semantics working together, so some explanations (that cause big problems for Transformational Grammar) are really easy and natural.
