For instance:
senci
has only one argument, so it's an intransitive predicate with a subject.
sumne has two arguments, one of which is defined as
"experiencer" and as the x1, but it's not unambiguously the agent (the
participant in a situation
that carries out the action in this situation) so long as the x2 can be
considered as the primary cause of the experience of smelling but yet
not unambiguously as the agent either from a common viewpoint. According
to Wikipedia, the linguist David Dowty suggests (
http://en.wikipedia.org/wiki/Agent_%28grammar%29)
that, in
His energy surprised everyone.
,
His energy is
the agent, "even though it does not have most of the typical agent-like
qualities
such as perception, movement, or volition". From that viewpoint, it
would be reasonable to say
sumne's x2 is the agent. In fact, the
gimste offers varying definitions in terms of the arguments' roles:
a.
x1 smells/scents x2 b.
x2 smells/has odor/scent to
observer x1And the interpretation of cases starts to appear
even more undecided/speaker-dependent when we take into account the
following situation.
If native English speakers see
da sumne de, they would
probably generally take the definition (a) and consider the x1
nominative:
[NOMINATIVE] [verb] [ACCUSATIVE]The
same for native Japanese speakers, despite their different word order:
[NOMINATIVE] [ACCUSATIVE] [verb]But what if native
Basque speakers see
da de sumne? It syntactically corresponds to
the Basque ergative allignment:
[ERGATIVE] [ABSOLUTIVE]
[verb]
That is, they would by tendency see
de (
sumne's x2) in
the same way that they see an intransitive predicate's subject like the
x1 of
blabi;
da blabi syntactically corresponds in Basque
to
[ABSOLUTIVE] [verb]And it's the same for predicates
the x1 of which appears in the English version of the gimste as
nominative and the x2 as accusative, such as
viska:
x1
sees/views/perceives visually x2 under conditions x3
For Basque speakers, this x2 would naturally appear as
absolutive and they would treat it in the same way as they would treat
an intransitive predicate's x1 and describe it as such if they ever make
a Lojban-Basque dictionary. Wikipedia has a Basque example of
The
man saw the boy. (
http://en.wikipedia.org/wiki/Ergative%E2%80%93absolutive_language#Morphological_ergativity):
Gizonak mutila ikusi du.
[gizon-ak] [mutil-a] [ikusi du]
[man-ERG]
[boy-ABS] [saw]
, which naturally corresponds to
[lo
nanmu] [lo nanla] [pu viska]Unlike Esperanto, Lojban does
not morphologically (and syntactically, for that matter) mark cases, so
the interpretation is usefully up to the listener/reader.

usually corresponds to the agent, just like the subject case in

nominative-accusative.
Whether or not a transitive
predicate's x1 is the agent does not at least in the above examples
affect Basque speakers' interpretation of the x2-case;
gizonak is
the agent, but it's of ergative case, and
mutila of absolutive
case. And there is nothing which would prohibit them from interpreting
lo
nanmu lo nanla pu viska in the same native scheme of theirs. Even
if
lo nanmu is explicitly marked as the agent with
gau,
they would associate it with their native eargative marker
-ak,
while native Japanese speakers would associate it with their nominative
marker
-ga.
For
one thing, Lojban has certain characteristics of fluid-S, a subtype of
active-stative. Wikipedia defines fluid-S (
http://en.wikipedia.org/wiki/Active_stative)
as:
[...] the marking of the
intransitive argument is decided by the speaker based
on semantic considerations. That is, for any given intransitive
verb the speaker may choose whether to mark
the subject as agentive or patientive, with agentive marking implying a
degree of volition or control, and patientive
implying lack of volition or control, suffering, or sympathy on the part
of the speaker.
Consider single-argument intransitive
predicates like
sipna. In
da sipna,
da, unmarked,
is either agentive or patientive: when
da ri'a sipna, it's
patientive; when
da segau sipna, it's agentive.
It's the same for multiple-argument intransitive predicates like
sakli.
In
da sakli de,
da, unmarked, is again either agentive or
patientive: when
da ri'a sakli de, it's patientive; when
da
segau sakli de, it's agentive.
Also,
tu'a and
jai can make the intransitive argument
either the agent or the object of a transitive verb -- the arbitrary
marking of which is what is commonly defined as the main feature of
active-stative.
