Specifically, these three forms were deletion of the copula, deletion of the auxiliary, and subject - verb variation.
In essence, this decision results in a distinction between copula and auxiliary functions of is and are.
For the dependent variable of zero copula, there are three variants.
Figure 3 summarizes the distributions of the zero copula by following grammatical environment.
Especially the copula seems to ensure that the subject and the predicate are in a definite logical relationship.
They never attempt to invert main verbs (other than copula be).
At the same time, we did see development in language-specific inflectional morphology and syntax required for copulas and lexical main verbs.
The first finite forms usually are modals and the copula\auxiliary is, supplemented by a limited set of stative lexical verbs.
Main verbs have meanings related to actions, events and states. Most verbs in English are main verbs:
Some main verbs are called linking verbs (or copular verbs). These verbs are not followed by objects. Instead, they are followed by phrases which give extra information about the subject (e.g. noun phrases, adjective phrases, adverb phrases or prepositional phrases). Linking verbs include:
