Al bivio scegliamo il sentiero a sinistra.

Al is the contraction of a + il.

• a can mean at, to, or in, depending on context
• il means the

So al bivio literally means at the fork / at the crossroads.

This kind of contraction is very common in Italian:

• a + il = al
• a + lo = allo
• a + la = alla
• a + i = ai
• a + gli = agli
• a + le = alle

Bivio usually means a fork, junction, or crossroads, especially a place where you have to choose between two directions.

In a hiking context, al bivio is very naturally understood as at the fork in the path.

It can also be used figuratively, like at a turning point in life.

Scegliamo is the 1st person plural form of the verb scegliere, which means to choose.

So it means we choose.

The present tense forms of scegliere are:

• io scelgo = I choose
• tu scegli = you choose
• lui/lei sceglie = he/she chooses
• noi scegliamo = we choose
• voi scegliete = you all choose
• loro scelgono = they choose

A learner may notice that the verb changes quite a lot from form to form. That is normal for this verb.

Yes, in the right context it can feel like let’s choose or we choose.

Grammatically, scegliamo is the present tense we choose, but Italian often uses this same form to make a suggestion involving we, especially in spoken language.

So depending on context:

• Scegliamo il sentiero a sinistra. could be We choose the path on the left
• or Let’s take/choose the path on the left

If the sentence is presented on its own, both readings are possible, though we choose is the most direct grammatical interpretation.

Il sentiero means the path.

Italian uses definite articles very often, sometimes more often than English does. Here, the sentence refers to a specific path: the one on the left.

So:

• il sentiero = the path
• un sentiero = a path

If you said un sentiero a sinistra, it would sound more like a path on the left, not a clearly identified one.

Because a sinistra is a fixed expression meaning on the left or to the left.

In this phrase, sinistra functions more like an adverbial expression of direction/location, so you normally do not use the article.

Common expressions are:

• a sinistra = on the left / to the left
• a destra = on the right / to the right

So:

• il sentiero a sinistra = the path on the left

Using alla sinistra here would usually sound unnatural.

Yes. Il sentiero di sinistra is also possible and often means essentially the same thing: the left-hand path.

Comparison:

• il sentiero a sinistra = the path on the left
• il sentiero di sinistra = the left-hand path

The difference is small in many contexts.
A sinistra emphasizes position more directly.
Di sinistra can sound a little more like classification: the left one.

Both are natural.

Italian often places a time or place expression at the beginning of the sentence to set the scene.

So:

• Al bivio scegliamo il sentiero a sinistra. literally: At the fork, we choose the path on the left.

This word order sounds natural and helps establish where the action happens before saying what is chosen.

You could also say:

• Scegliamo il sentiero a sinistra al bivio

But the original version is more natural if you want to foreground the location.

A common difficulty is the gli sound.

Very roughly, scegliamo is pronounced something like:

SHEH-lya-mo

More exactly:

• sc before e/i sounds like sh
• gli is a special Italian sound, similar to the lli in some pronunciations of million, but smoother and more distinctly Italian

So:

• sce- sounds like sheh
• -glia- sounds like lya
• -mo sounds like mo

This is one of those sounds that takes practice.

Sentiero usually means a path, trail, or footpath, especially a narrow one in nature.

So in this sentence it strongly suggests something like:

• a hiking path
• a trail through the woods or hills
• a narrow route for walking

If it were a road, Italian would more likely use words like strada or via, depending on context.

Because Italian usually does not need subject pronouns when the verb ending already shows the subject.

Here, scegliamo already tells you the subject is we.

So:

• scegliamo = we choose
• noi scegliamo = we choose, but with extra emphasis

Italian often omits pronouns unless they are needed for:

• emphasis
• contrast
• clarity

For example:

• Noi scegliamo il sentiero a sinistra, loro quello a destra. = We choose the path on the left, they choose the one on the right.

Yes. Italian a sinistra can cover both ideas, and the exact meaning depends on context.

Examples:

• Gira a sinistra = Turn left
• La banca è a sinistra = The bank is on the left
• il sentiero a sinistra = the path on the left

So in your sentence, it naturally describes the path located on the left side at the fork.

Yes. Italian often uses the present tense for actions happening now, for habitual actions, and sometimes for vivid narration.

So scegliamo is grammatically present tense, but in context it can describe:

• what we are doing now
• what we usually do at that point
• a step in instructions or narration

For example, in route instructions, Italian often uses the present:

• Al bivio prendiamo la strada a destra.
• Poi attraversiamo il ponte.

This is very natural and often corresponds in English to either the present or an instruction-like style.
