Interest and Réfert.
355.
The impersonals interest and réfert take the Genitive of the person
(rarely of the thing) affected.
The subject of the verb is a neuter pronoun or a substantive clause:
- Clodí intererat Milónem
períre (cf. Mil. 56), It was the interest of Clodius that
Milo should die.
- aliquid quod illórum mágis
quam suá rétulisse vidérétur
(Iug. 111), something which seemed to be more for their interest than
his own.
- videó enim quid meá intersit,
quid utríusque nostrum (Fam. vii. 23. 4), for I see
what is for my good and for the good of us both.
a. Instead of the genitive of a personal
pronoun the corresponding possessive is used in the ablative singular
feminine after interest or refert:
- quid tui id réfert ?
magni (Ter. Ph. 723), how does that concern you? much.
[See also the last two examples above.]
- vehementer intererat vestrá
quí patrés estis (Plin, Ep. iv. 13. 4), it would
be very much to your advantage, you who are fathers.
NOTE: This is the only construction with refert in
classic prose, except in one passage in Sallust (see example above).
b. The accusative with ad is used with interest and refert
to
express the thing with reference to which one is interested:
- mágni ad honarem nostrum
interest (Fam. xvi. 1), it is of great consequence to our
honor.
- réfert etiam ad
fructús (Varr. R. R. i. 16. 6), it makes a difference as
to the crop.
NOTE 1: Very rarely the person is expressed by ad and the accusative, or with refert by the dative (probably a popular corruption): -
- quid id ad me aut ad meum rem
refert (Pl. Pers. 513), what difference does that make to me or
to my interests?
- quid referat intra náturae
fínís viventí (Hor. S. i. 1. 49), what
difference does it make to me who live within the limits of natural
desire?
- non referre dedecorí
(Tac. Ann. xv. 65), that it makes no difference as to the
disgrace.
NOTE 2: The degree of interest is expressed by a genitive of
value, an adverb or an adverbial accusative.
