pium: explained by v. 3 f.
 parata manent tibi: i. e. are from now on yours to enjoy; on manere with the dative cf. Catul. 8.15n. tibi manet. In his despair Catullus speaks as if the chapter of his active life were closed, and nothing were left him but the reminiscent period of old age.
 cuiquam: one of the less frequent cases where quisquam occurs when no negative is either used or implied; but perhaps here the preceding quaecumque suggesting an idea of contingency (= si qua) is sufficient to prompt the use of cuiquam.
 ingratae … menti: cf. Catul. 65.16f.; the adjective is here active, and not passive as in v. 6.
 animo offirmas: a phrase apparently not occurring elsewhere, though approximated by, e.g., Pl. Merc. 82 “animum offirmo meum” ; Ter. Eun. 217 “censen posse me offirmare perpeti” ; Ov. Met. 9.745 “quin animum firmas teque ipsa recolligis” ; Plin. Ep. 7.27.8 “offirmare animum” .
 -que: correlative with v. 12 et; the recovered soul-courage is to be shown by abandoning once for all his unworthy passion, and, as a consequence, by regaining his peace of mind. With -que appended to the second word of its clause cf. Catul. 57.2.
