Institutio Oratoria

So too we get the Latinised genitives Ulixi and Achilli together with many other analogous forms. More recent scholars have instituted the practice of giving Greek nouns their Greek declension, although this is not always possible. Personally I prefer to follow the Latin method, so far as grace of diction will permit. For I should not like to say Calypsonem on the analogy of Iunonem, although Gaius Caesar in deference to antiquity does adopt this way of declining it. Current practice has however prevailed over his authority.

In other words which can be declined in either way without impropriety, those who prefer it can employ the Greek form: they will not be speaking Latin, but will not on the other hand deserve censure. Simple words are what they are in the nominative, that is, their essential nature.

Compound

For I will not admit that the combination of three is possible at any rate in Latin, although Cicero asserts that capsis [*](Orat. xlv. 154. ) is compounded of cape si vis, and there are to be found scholars who contend that Lupercalia likewise is a compound of three parts of speech, namely luere per caprum.

As for Solitaurilia it is by now universally believed to stand for Suovelaurilia, a derivation which corresponds to the actual sacrifice, which has its counterpart in Homer [*]( As in Od. xi. 130. The word means sacrifices of a pig, sheep and bull. ) as well. But these compounds are formed not so much from three words as from the fragments of three. On the other hand Pacuvius seems to have formed compounds of a preposition and two vocables ( i.e. nouns) as in

1. Nerei repandirostrum incurvticervicum pecs:

1. The flock
2. Of Nereus snout-uplifted, neck-inarched

Compounds are however formed from two complete Latin words, as for instance supefui and subterfui; though in this case there is some question as to whether the words from which they are formed are complete. [*](i.e. if both elements are complete in themselves is the word a true compound? ) They may also be formed of one complete and one incomplete

In the case of prepositions they are frequently changed by the act of compounding: as a result we get abstulit, aufugit, amisit, though the preposition is ab, and coil, though the preposition is con. The same is true of ignauus and erepublica. [*](Sometimes written as one word.) But compounds are better suited to Greek than to Latin,

though I do not think that this is due to the nature of our language: the reason rather is that we have a preference for foreign goods, and therefore receive κυρταύχην with applause, whereas we can scarce defend incurvicervicus from derisive laughter. Words are proper when they bear their original meaning;

metaphorical, when they are used in a sense different from their natural meaning. Current words are safest to use: there is a spice of danger in coining new. For if they are adopted, our style wins but small glory from them; while if they are rejected, they become a subject for jest.

Still we must make the venture; for as Cicero [*](de Nat. deorum, I. xxxiv. 95. ) says, use softens even these words which at first seemed harsh. On the other hand the power of onomatopoeia is denied us. Who would tolerate an attempt to imitate

the bow twanged,

the eye hissed

to baa,

to whinny,

There are special rules which must be observed both by speakers and writers. Language is based on reason, antiquity, authority and usage. Reason finds its chief support in analogy and sometimes in etymology. As for antiquity, it is commended to us by the possession of a certain majesty, I might almost say sanctity.

Authority as a rule we derive from orators and historians. For poets, owing to the necessities of metre, are allowed a certain licence except in cases where they deliberately choose one of two expressions, when both are metrically possible, as for instance in imo de stirpe recisum and aeriae quo congessere palumbes or silice in nuda [*](Aen. xii. 208: cutaway from the lowest root. Ecl. iii. 69: where airy doves have made their nest. Ecl. i. 15: on the naked rock. Stirps, palumbes and silex are usually masculine. ) and the like. The judgment of a supreme orator is placed on the same level as reason, and even error brings no disgrace, if it result from treading in the footsteps of such distinguished guides.

Usage however is the surest pilot in speaking, and we should treat language as currency minted with the public stamp. But in all these cases we have need of a critical judgment, especially as regards analogy (a Greek term for which a Latin equivalent has been found in proportion).

The essence of analogy is the testing of all subjects of doubt by the application of some standard of comparison about which there is no question, the proof that is to say of the uncertain by reference to the certain. This can be done in two different ways: by comparing similar words, paying special attention to their final syllables

Comparison of nouns will reveal either their gender or their declension: in the first case, supposing the question is raised as to whether junis be masculine or feminine, panis will supply a standard of comparison: in the second case, supposing we are in doubt as to whether we should say hac domu or hac domo, domuum or domorum, the standard of comparison will be found in words such as anus or manus.
