substantive in old Latin, (_b._) with verbs of motion, #eō#, #veniō#,
#currō#, #mittō#, in old or poetical Latin, and (_c._) in the
combination #dō bibere#, _give to drink_, in old, colloquial, or
poetical Latin: as,
(_a._) #occāsiō benefacta cumulāre#, Pl. _Cap._ 423, _a chance to pile
up kindnesses_. Parallel with a gerund: #summa ēlūdendī occāsiōst mihi
nunc senēs et Phaedriae cūram adimere argentāriam#, T. _Ph._ 885, _I’ve
now a splendid chance the greybeards of eluding and Phaedria to rescue
from his money cares_. (_b._) #recurre petere rē recentī#, Pl. _Tri._
1015, _run back to get it ere it is too late_. #voltisne eāmus vīsere?#

nudiusquārtus Cāriam petere argentum#, Pl. _Cur._ 206, _my parasite I
sent four days ago to Caria, to fetch the cash_. #nec dulcēs occurrent
ōscula nātī praeripere#, Lucr. 3, 895, _nor shall thy children dear come

hearths_. (_c._) #bibere dā usque plēnīs cantharīs#, Pl. _Per._ 821,
_keep giving on to drink with brimming bowls_. #bibere# is thus used by
Plautus, Terence, Cato, and Livy, and by Cicero once with #ministrō#. In
classical prose, purpose is expressed by the subjunctive with #ut# or a
relative pronoun, or by a gerund or gerundive with #ad# or #causā#.
