tive
Singular Neuter of Pronouns, or of Adjectives used substantively; also with
the Adverbs parum, satis, and partim when used substantively; as,--

quid consili, _what purpose?_

tantum cibi, _so much food_;

plus auctoritatis, _more authority_;

minus laboris, _less labor_;

satis pecuniae, _enough money_;

parum industriae, _too little industry_.

a. An Adjective of the second declension used substantively may be
employed as a Genitive of the Whole; as, nihil boni, _nothing good_.

b. But Adjectives of the third declension agree directly with the noun
they limit; as, nihil dulcius, _nothing sweeter_.

3. Occasionally we find the Genitive of the Whole dependent upon Adverbs of
place; as,--

ubi terrarum? ubi gentium? _where in the world?_

a. By an extension of this usage the Genitive sometimes occurs in
dependence upon pridie and postridie, but only in the phrases pridie ejus
diei, _on the day before that_; postridie ejus diei, _on the day after
that_.

202. Appositional Genitive. The Genitive sometimes has the force of an
appositive; as,--

nomen regis, _the name of king_;

poena mortis, _the penalty of death_;

ars scribendi, _the art of writing_.

203. Genitive of Quality. The Genitive modified by an Adjective is used to
denote quality. This construction presents several varieties. Thus it is
used--

1. To denote some internal or permanent characteristic of a person or
thing; as,--

vir magnae virtutis, _a man of great virtue_;

rationes ejus modi, _considerations of that sort_.

a. Only a limited number of Adjectives occur in this construction,
chiefly magnus, maximus, summus, tantus, along with ejus.

2. To denote measure (_breadth_, _length_, etc.); as,--

fossa quindecim pedum, _a trench fifteen feet wide_ (or _deep_);

exsilium decem annorum, _an exile of ten years_.

3. Equivalent to the Genitive of Quality (though probably of different
origin) are the Genitives tanti, quanti, parvi, magni, minoris, pluris,
minimi, plurimi, maximi. These are used predicatively to denote _indefinite
value_; as,--

nulla studia tanti sunt, _no studies are of so much value_;

magni opera ejus existimata est, _his assistance was highly esteemed_.

4. By an extension of the notion of _value_, quanti, tanti, pluris, and
minoris are also used with verbs of _buying_ and _selling_, to denote
_indefinite price_; as,-
