Institutio Oratoria

I turn to tile discussion of ambiguity, which will be found to have countless species: indeed, in the opinion of certain philosophers, there is not a single word which has not a diversity of meanings. There are, however, very few genera, since ambiguity must occur either in a single word or in a group of words.

Single words give rise to error, when the same noun applies to a number of things or persons (the Greeks call this homonymy): for example, it is uncertain with regard to the word gallus whether it means a cock or a Gaul or a proper name or an emasculated priest of tybele; while Ajax may refer either to the son of Telamon or the son of Oileus. Again, verbs likewise may have different meanings, as, for example, cerno. [*]( See or decide or separate. )
