auxiliary (function word) is a substitution value (cf. NLC'06, Sect. 6.4), while
that of a main verb is a concept. Non-finite verb forms differ from finite ones
by the absence of the constant
v
at the end of their
cat
value. The verbal moods
of the
indicative, subjunctive,
and
imperative
are coded as the
sem
values
ind,
sbjv,
and
impv
, respectively (Sect. 5.6; Quirk et al. (1985:149-150)).
There remain the traditional parts of speech
7. conjunction
and
8. interjec-
tion
. Conjunctions are function words which are used for connecting expres-
sions of the same part of speech (coordination, parataxis, cf. NLC'06, Chaps.
8 and 9) or of different part of speech (subordination, hypotaxis, NLC'06,
Chap. 7). Interjections are one-word sentences; their lexical analysis is not
constrained by the compositional considerations of establishing semantic re-
lations and they still await analysis as proplets in Database Semantics.
In summary, despite our using only three core attributes in DBS, the tra-
ditional parts of speech may be reconstructed using other properties. For ex-
ample, based on the lexical analysis of word forms in 3.5.2,
pronouns
as a
traditional part of speech are characterized by an indexical core value, while
determiners
have a substitution variable instead. Similarly, based on the lexical
analysis in 3.5.3,
prepositions
as a traditional part of speech are characterized
by the cat value
adnv
and a substitution variable as their core value, adnomi-
nals by the cat value
adn
and a concept as their core value, indexical adverbs
by the cat value
adv
and a pointer as their core value, and so on.
These grammatical distinctions may be easily used to lexically define word
forms as proplets which have precisely the properties desired: Just invent a
nice attribute name and the associated value(s), and put them into your DBS
system. The grammatical distinctions are also used in the automatic defini-
tion of schemata for equally precise retrieval from the Word Bank. Like all
schemata, they constitute a particular
view
on the data (Sect. 4.5).
Finally, another remark on terminology. DBS distinguishes between the
three parts of speech
noun, verb
,and
adj
, and between the three levels of
complexity
elementary, phrasal
,and
clausal
(Hausser 2009). These are or-
thogonal to each other and combine as follows:

verb
barked could have barked Fido barked.
adj

Accordingly, we say “phrasal noun” when we mean something like
the man
in the brown coat
rather than “noun phrase,” except in the discussion of the
