Institutio Oratoria

Again, another source of ambiguity arises from leaving it doubtful in a written document whether a syllable is long or short. Cato, for example, means one thing in the nominative when its second syllable is short, and another in the dative or ablative when the same syllable is long. [*](sc. of the adjective catus, shrewd. ) There are also a number of other forms of ambiguity which it is unnecessary for me to describe at length.

Further, it is quite unimportant how ambiguity arises or how it is remedied. For it is clear in all cases that two interpretations are possible, and as far as the written or spoken word is concerned, it is equally important for both parties. It is therefore a perfectly futile rule which directs us to endeavour, in connexion with this basis, to turn the word in question to suit our own purpose, since, if this is feasible, there is no ambiguity.
