Слово встречается в следующем контексте:

The syntactic frame of a given LF f provides
two types of information on possible values of
f(L):
1. their part of speech —there are only four
parts of speech: V(erb), N(oun), A(djective)
and Adv(erb);
2. their diathesis —that is, the list of their syntactic
dependents in increasing order of oblicity.
For instance, the formula V[2,1] denotes a
verbal value for f(L) taking the second (semantic)
actant of the keyword L as subject and its
first actant as first complement.
