3. But when a predicate noun is of different gender or number from its subject, the verb usually agrees with its nearest substantive; as,—
Tarquiniī māterna patria erat, Tarquinii was his native country on his mother's side;
nōn omnis error stultitia est dīcenda, not every error is to be called folly.
a. Less frequently the verb agrees with an appositive; as,—
Coriolī, oppidum Volscōrum, captum est, Corioli, a town of the Volsci, was captured.
4. Construction according to Sense. Sometimes the verb agrees with its subject according to sense instead of strict grammatical form. Thus:—
a) In Number; as,—
multitūdō hominum convēnerant, a crowd of men had gathered.
b) In Gender; as,—
duo mīlia crucibus adfīxī sunt, two thousand (men) were crucified.
