The copula hinnegeango selects a Verb-Initial infinitival clause. The infinitival verb in clause-initial position has neither the form of an ordinary infinitive nor that of a gerundial infinitive. Instead, it is homophonous to the imperative form of the verb. An example is given below:

The example cannot be analysed as a coordination of two tensed verbs, since the second verb does not bear third person agreement nor does it exhibit past tense morphology. Furthermore, the meaning of the sentence is such that the verb stjoersend is semantically in the scope of both the modal verb koecould and the copula verb hinnegeango. It can further be shown that the infinitival verb stjoersend is selected by hinnegeango and not by the modal, since the modal does not select Verb-Initial infinitives, as shown below:

A Verb-Initial ordinary infinitive is similarly excluded, as is a gerund, since these types of infinitives are not allowed to precede the arguments which they subcategorize for:

It must be mentioned that the use of hinnegeango is quite old-fashioned, being restricted to older written Frisian.
