Would you be kind enough to tell me whether the word in bold in the following excerpt from the Nietzsche’s “Beyond Good and Evil” is in common use in the contemporary English language?
As in the stellar firmament there are sometimes two suns which determine the path of one planet, and in certain cases suns of different colours shine around a single planet, now with red light, now with green, and then simultaneously illumine and flood it with motley colours: so we modern men, owing to the complicated mechanism of our "firmament," are determined by DIFFERENT moralities; our actions shine alternately in different colours, and are seldom unequivocal--and there are often cases, also, in which our actions are MOTLEY-COLOURED.
equivocal = ambiguous, confusing, dubious, evasive, indefinite, misleading, oblique, obscure, uncertain, vague.
Thank you for your efforts.
Both equivocal and unequivocal are used fairly commonly, but usually in reasonably formal writings and speech.
