Introduction
perfective
verb phrases denote whole completed processes, while imperfective ones
designate processes in progress. […] imperfective verb phrases may also have
repetitive or habitual meanings. – 141
Langacker’s
idea that the grammar of a language should be characterized as “those aspects
of cognitive organization in which resides a speaker’s grasp of established
linguistic convention” (1987a: 57) or as “a structured inventory of
conventional linguistic units (ibid), where a unit is understood as any
semantic, phonological or symbolic structure mastered by a native speaker to
such an extent that it becomes cognitive routine for him. (cf. Langacker 1988a:
11) - 141
Such an
understanding of the notion of grammar leads, among other things, to granting
the status of a unit to any meaning of a given linguistic structure arising in
a specific context of use, provided that this meaning is sufficiently
conventionalized for a sufficient number of speakers of a language (cf.
Langacker 1988a: 11). – 142
According
to Langacker, process type may be classified into two main groups: those that
are conceptualized as being bounded in time within the viewing frame and those
that are thought of as temporally unbounded. – 143t
According
to Langacker, a process type is bounded not only if it inherently involves the
conception of a terminal point, whose attainment results in completing the
process in question. A process type is temporally bounded simply if its
component states are normally thought of as being distributed over a limited
span of time and its temporal boundaries are conceptualized as falling within
the adopted viewing frame. – 143
It is
important to stress here that what matters for classifying a process type as
either temporally bounded or unbounded is how this process is typically
conceptualized. – 143
A
process type is internally heterogeneous if its component states are changing
through time. On the other hand, a process type is internally homogeneous if
all its component states are “Construed as being effectively identical.” – 143
On the
points that he (Verkuyl) raises is that this notion (of homogeneity) is useless
is differentiating sentences which are durative in his analysis – such as John
pushed a cart – from sentences that he classifies as terminative – such as John
ate a piece of fruit-cake. The sentence is classified as durative because
it can combine with a for+NPspan of time adverbial and cannot
combine with an in+NPspan of time adverbial. The second
sentence behaves in the opposite way and is thus classified as terminative. […]
Nevertheless, both sentences are said to be characterized by homogeneity since
both cases if x V-ed is true for any interval of time, it is also true
for any portion of this interval. Therefore, the notion of homogeneity is said
to be irrelevant for aspectual consideration. -144-45
Answer
to criticism of this kind is that, first of all, under Langacker’s
understanding of the notion of homogeneity, it is only the process instance
profiled by John pushed the cart that is internally homogenous. On the
other hand, the process instance profiled by John at a piece of fruit-cake
is internally homogeneous since in each component phase of this process its
landmark (a piece of fruit-cake) gets smaller and smaller as a result of what
the trajectory (John) does. Therefore, the profiled relationship between
the process participants is construed as changing through time. – 145
The
notion of internal homo- or heterogeneity may be useful in explaining the
behavior of verb phrases combined with for+NPspan of time and
in+NPspan of time adverbials. – 145
According
to Langacker every verbal stem profiles a process type. – 146
Internally
homogeneous and temporally unbounded e.g. have black hair.
Internally
heterogeneous and temporally bounded e.g. repair a car, read a letter.
Internally
homogeneous nevertheless temporally bounded e.g. sleep, read

An analysis of the data
According
to Langacker, coordination in its pure form, such as coordination by means of
the logical and, “reduces to the mental juxtaposition of co-equal
structures, on either a simultaneous or an alternating basis” (1991: 472). This
means that no relationship between (or among) the coordinated entities
constitutes an object of conceptualization but their mental juxtaposition is
just a part of the conceptualization process. – 147

Conclusions
When a
number of verb phrases are coordinated in a sequence, such a construction
usually exhibits meanings that go beyond the purely compositional
interpretation. One such constructional meaning is the meaning of some temporal
relationship, such as simultaneity or sequentiality, between the profiled
process instances. – 159
Perfective
and imperfective verb phrases are polysemous and, cannot be reduced to a single
semantic representation but rather constitute networks of interrelated senses. –
161
The meaning
of a perfective or an imperfective verb phrase cannot be analyzed as the sum of
the meaning of a verbal stem and the perfective or the imperfective morpheme.
This is because the aspectual interpretation of a verb phrase heavily depends
on a sentential and discourse context in which this phrase is used. - 162
