Syntax of the adjective and types of texts in classical Greek. Constructions meaning "it is obvious that"

In Ancient Greek, certain formal features of non-attributive adjectives seem to vary according to the literary genre in which they are used. The aim of this paper is to assess if this provides a good explanation for the existence of several constructions meaning "it is obvious that" and containing adjectives such as delta eta lambda omicron sigma, phi alpha nu epsilon rho omicron sigma, etc. This is done by analysing the frequency and the syntactic characteristics of each of the attested constructions. The existence of the type delta eta lambda omicron sigma epsilon iota mu iota omicron tau iota ... "it is obvious that I ..." draws attention to the need to take into account the factors governing the use of each type of complement clause in these constructions, since they seem to be partially independent from the form taken by the adjective.
