Salpiamo oggi e ormeggiamo stasera.

Both are 1st person plural, present indicative forms:

• salpiamo = we set sail / we sail
• ormeggiamo = we moor / we dock

Their infinitives are:

• salpare = to set sail
• ormeggiare = to moor, to dock, to berth

So grammatically, the sentence is built with two present-tense we forms joined by e = and.

Italian often uses the present tense for a planned, scheduled, or near-future action, especially when a time expression makes the meaning clear.

So Salpiamo oggi e ormeggiamo stasera literally uses the present, but in natural English it may correspond to:

• We set sail today and dock tonight
• We're setting sail today and docking tonight
• We'll set sail today and dock tonight

Because oggi and stasera clearly place the actions in time, Italian does not need a future tense here.

Because Italian normally drops subject pronouns when they are already clear from the verb ending.

• salpiamo already means we set sail
• ormeggiamo already means we dock / we moor

So noi is unnecessary unless you want emphasis or contrast.

For example:

• Noi salpiamo oggi, loro domani.
  We sail today, they tomorrow.

In your sentence, leaving out noi is the most natural choice.

They both mean this evening / tonight.

• stasera is a very common, compact form
• questa sera is also correct and may sound a little fuller or more explicit

So these are both natural:

• Ormeggiamo stasera.
• Ormeggiamo questa sera.

In everyday Italian, stasera is extremely common.

No. In Italian, time words like oggi and stasera usually appear without a preposition.

So you say:

• oggi = today
• stasera = tonight / this evening

Not:

• in oggi
• a stasera in this meaning

This is one place where Italian is simpler than English, since English often needs words like on, in, or at in other contexts.

Yes, you could absolutely say Oggi salpiamo e stasera ormeggiamo.

Italian word order is fairly flexible. The original sentence:

• Salpiamo oggi e ormeggiamo stasera

is neutral and natural.

If you move the time expressions forward:

• Oggi salpiamo e stasera ormeggiamo

you give slightly more emphasis to when the actions happen.

So both are correct; the difference is mainly one of focus and style.

A simple English-friendly approximation is:

• salpiamo ≈ sal-PYAH-mo
• ormeggiamo ≈ or-meg-JAH-mo

A few pronunciation notes:

• In salpiamo, the stress falls on -pia-
• In ormeggiamo, the stress falls on -gia-
• The gi sound in ormeggiamo is like the j in jam
• The double gg means the consonant is held a bit longer than a single g

Also, Italian pronunciation is usually very regular, so once you know the spelling rules, these forms become easier to read aloud.

Yes, but these two verbs are more nautical and specific.

• salpare specifically means to set sail or leave port
• ormeggiare specifically means to moor / berth / dock a boat

More general verbs would be things like:

• partire = to leave, to depart
• arrivare = to arrive
• attraccare = to dock, pull alongside

So Salpiamo oggi e ormeggiamo stasera sounds appropriately maritime. It suggests a boat or ship, not just general travel.

In isolation, the Italian present can sometimes express either:

• a habit: something people regularly do
• a current or planned event

But here, the time words oggi and stasera strongly point to a specific plan for today, not a repeated habit.

So the most natural reading is:

• We’re setting sail today and docking tonight

If the sentence were describing a routine, it would normally need different context, such as repeated time expressions or a broader description.
