La vojon elektinta amikino gvidas nin al la hotelo.

In standard Esperanto, it should almost certainly be elektinta, from the verb elekti = to choose.

So the sentence is best understood as:

La vojon elektinta amikino gvidas nin al la hotelo.

A native English speaker may expect something like elect- because of English, but Esperanto uses k here: elekti, elektis, elektinta.

Elektinta is the past active participle of elekti.

• elekti = to choose
• elektinta = having chosen / who chose

In this sentence, it describes amikino, so it means:

the female friend who chose the route/path

A very natural English equivalent is who chose, even though the literal structure is more like having chosen.

Because it is acting like an adjective and describing the noun amikino.

Esperanto participles can behave like adjectives, nouns, or adverbs:

• -a = adjective
• -o = noun
• -e = adverb

So here:

• elektinta amikino = a friend who has chosen / who chose

Since it modifies amikino, it takes the adjective ending -a.

Because vojon is the direct object of elekti inside the participial phrase.

The structure is:

• elekti la vojon = to choose the route
• la vojon elektinta amikino = the friend who chose the route

Even though elektinta is being used adjectivally, it still keeps its own object, and that object is marked with -n:

• la vojo = the route
• la vojon = the route as a direct object

So vojon is not the object of gvidas; it belongs to elektinta.

Because amikino is the subject of the main verb gvidas.

The sentence breaks down like this:

• La vojon elektinta amikino = the female friend who chose the route
• gvidas = guides / is guiding
• nin = us
• al la hotelo = to the hotel

So the friend is the one doing the guiding. That makes amikino the subject, so it stays in the basic -o form.

Because nin is the direct object of gvidas.

• gvidi iun = to guide someone
• nin = us

So:

• amikino gvidas nin = the friend guides us

This is a separate accusative from vojon. The sentence contains two different object relationships:

1. vojon belongs to elektinta
   → chose the route
2. nin belongs to gvidas
   → guides us

Yes. A very clear equivalent is:

La amikino, kiu elektis la vojon, gvidas nin al la hotelo.

or, without commas in a more restrictive reading:

La amikino kiu elektis la vojon gvidas nin al la hotelo.

This means essentially the same thing. The participle version is more compact:

• la vojon elektinta amikino
• the friend who chose the route

For many learners, the kiu elektis version is easier to understand at first.

Because in Esperanto, a participle can keep its own complements, and they can come before it:

• la vojon elektinta amikino

This is a compact way of saying:

• la amikino, kiu elektis la vojon

It may feel unusual to an English speaker because English normally says the friend who chose the route, not the route-chosen friend. But Esperanto allows this kind of structure quite naturally.

Yes, to a degree.

Because Esperanto marks grammatical roles clearly with endings like -n, word order is more flexible than in English. For example, the relative-clause version can be rearranged more easily without losing clarity.

Still, some orders are more natural than others. In this sentence, la vojon elektinta amikino is a standard compact participial phrase.

For learners, the safest way to understand it is not word by word in English order, but as one unit:

la vojon elektinta amikino = the friend who chose the route

Because al means to, toward, and it already shows direction.

• al la hotelo = to the hotel

In Esperanto, nouns after prepositions normally do not take -n just because of motion, since the preposition already shows the relationship.

So here:

• gvidas nin al la hotelo = guides us to the hotel

That is the normal and straightforward wording.

Amikino specifically means female friend.

• amiko = friend / male friend
• amikino = female friend

The suffix -in- marks the feminine form.

So the sentence is talking about a female friend, not just a friend in general.

The participle would agree with the noun, just like an adjective.

For example:

• La vojon elektintaj amikinoj gvidas nin al la hotelo.

That means:

• The female friends who chose the route guide us to the hotel.

Notice the agreement:

• amikinoj = plural noun
• elektintaj = plural adjective-participle

This shows that participles used adjectivally follow the same agreement rules as ordinary adjectives.
