Let's put it to a vote.
'Voti' — VO-ti. Stress on the first syllable. 'Mettiamola' — met-TIA-mo-la. 'La' refers to 'la questione' (the matter).
Use when a group has argued long enough without resolution and a democratic decision is the most efficient way forward. Also used humorously in informal group settings.
'Mettere ai voti' (to put to votes = to put to a vote) uses the dative 'ai voti' (to the votes). It's the democratic resolution of disagreement. In Italian culture, voting is seen as the fair resolution of stubborn disagreements in groups.
Decidiamo a maggioranza.
Let's decide by majority.
'A maggioranza' (by majority) — specifies the decision rule. Standard democratic process.
Chi è favorevole alzi la mano.
Those in favour raise their hand.
Procedural — moves directly to the voting action. Used in meetings of all sizes.
Usiamo il voto per risolvere.
Let's use the vote to resolve it.
Explicitly names voting as the resolution mechanism — practical and final
Italian civic culture has a deep attachment to democratic voting ('il voto') as the ultimate resolution mechanism. From national elections to village committees to family holiday destinations, voting is seen as the fair and final way to resolve disagreement — even if the losers don't immediately accept the result.
