verb _est_, and the frequent use of the infinitive instead of a
dependent clause--for example, _hortatur dicere, res postulat exponere,
conjuravere patriam incendere_, and many similar expressions--arise
from his desire to be brief and concise. Among his antiquated forms of
words, we may mention _die_ for _diei_, the singular _plerusque_, _quis_
for _quibus_, _senati_ for _senatus_; _dicundi, legundi_, &c. for
_dicendi, legendi_; _intellego_ for _intelligo_, _forem_ for _essem_,
_fuere_ for _fuerunt_; the use of the past participles of deponent verbs
in a passive sense--as _adeptus, interpretatus_. Antiquated words, or
words used in an antiquated sense, are--_supplicium_ for _preces_,
_scilicet_ for _scire licet_; antiquated expressions are--_fugam facere_
for _fugere_, _habere vitam_ for _agere vitam_, and other phrases with
_habere_. The frequent use of _mortales_ for _homines_, _aevum_ for
_aetas_, and _subigere_ for _cogere_, gives to his style somewhat of a
poetical colouring. As far as grammatical construction is concerned,
there is a tendency to archaisms in the use of _quippe qui_ with the
indicative; in the frequent application of the indicative in subordinate
sentences in the oratio obliqua; and in some other points which we shall
explain in short notes to the passages where they occur. An intentional
disturbance of rhetorical symmetry is perceptible in the change of
corresponding particles;--for example, instead of _alii_ in the
expression _alii-alii_, we find _pars_ or _partim_; instead of _modo_ in
the expression _modo-modo_, we find _interdum_, and similar variations.
But all these differences from the ordinary language contain in
themselves sufficient grounds of explanation and excuse, and are by no
means so frequent as to render the language of Sallust unworthy of the
merited reputation of being classical.
