In English the Verb to be admits of an Adjective as its complement; in Kongo this is never the case, only Nouns or Adverbs (or Noun or Adverbial Clauses) can so serve; sometimes the Verb to be is transformed into the Verb to have (to be with), to get over the difficulty. Unless an Adverb is preferable, a Noun or Noun Clause corresponding to the adjectival idea in English is used; where the idea is participial, the Infinitive Noun serves to express it. In Relative Clauses the Particle vo follows immediately after the Verb to be, when a Noun is its complement.
