De Gruyter Mouton, 1970. — 224 p.
The present study is based on a corpus of 2600 examples drawn from 242 works of the last fifty years, most of the texts being plays and all of the examples representing conversation. The corpus has been held within certain formal bounds. The examples treated are all independent declarative clauses of inanimate reference, whose verb (always être) is in the present tense and whose predicative element is a true adjective, i.e., not a past participle, prepositional phrase or adverb (with the exception of bien and mal and their comparative forms).
