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. )

This ambiguity crops up in many ways, and gives rise to disputes, mole especially in connexion with wills, when two men of the same name claim their freedom or, it may be, an inheritance, or again, when the enquiry turns on the precise nature of the bequest.

There is another form of ambiguity where a word has one meaning when entire and another when divided, as, for example, ingenua, armameniam or Corvinum. [*](Inyenua, a freeborn woman; in genua, on to the knees. Armamentum, equipment; arma mentum, arms, chin. Corvinum, ace. of name Corvinus; cor vimium, heart, wine. ) The disputes arising from such ambiguities are no more than childish quibbles, but nevertheless the Greeks are in the habit of making them the subject for controversial themes, as, for example, in the notorious case of the αὐλητρίς, when the question is whether it is a hall which has fallen down three times ( αὔλη τρίς ) or a flute-player who fell down that is to be sold.

A third form of ambiguity is caused by the use of compound words; for example, if a man orders his body to be buried in a cultivated spot, and should direct, as is often done, a considerable space of land surrounding his tomb to be taken from the land left to his heirs with a view to preserving his ashes from outrage, an occasion for dispute may be afforded by the question whether the words mean

in a cultivated place

in an uncultivated place

Thus arises the Greek theme

1. I say that you, O prince of Aeacus' line,
2. Rome can o'erthrow.
