How do you express favor in Latin—what verbs, cases and constructions are on your plate? There are a few basic flavors the favor construction.
The most obvious construction is faveō + a dative object. This verb only rarely appears absolutely (without an object).
- Do you favor my resources, or those of Caesar: meīs rēbus favētis, aut Caesāris?
- He prefers the stillness of the evening hours: silentiō noctis favet.
Annuō + dative of person + accusative object usually means ‘to grant + someone + something’ but may also appear as annuō + dative of person and merely mean ‘to favor someone.’
- She favored the better cause: ratiōnī maiōri annuit.
Adiuvō + accusative ordinarily means ‘aid’ but may in certain oblique cases approach ‘favor.’
- Favor us with your prayers: nōs precibus adiuvā!

And remember annuit coeptis appears on the US $1 bill. Nice use of the dative case there.
