I didn't find this as 1ac as Basil's puzzle last week, ending up a bit baffled by 5ac, 12ac and a couple of spellings/word endings. But it was all in Latin and therefore good!
1 Easily, opp. vix (6)
5 Lit. heat of fire and sea swell, metaph. upset of mind (4th decl.) (6)
AESTUS. Can mean both "passion" and "hesitation" figuratively: so much for Latin being a logical language.

SUPERIOR. No different from the masculine, in this comparative form.
9 I change: vario (4)

10 He carries, also she relates (4)
FERT - repeat after me: ferro, ferre, tuli, latus.
11 To inhabit or live in (3rd conj.) (8)

3 Sloth, lack of skill, and in English now what keeps us going (7)
INERTIA or ART-lessness
