La manguera permite regar el bancal.

Because manguera is a feminine noun in Spanish, so it takes the feminine singular article la.

• la manguera = the hose
• una manguera = a hose

Even though many nouns ending in -a are feminine, that is just a common pattern, not the real reason. The real reason is simply that manguera is grammatically feminine, so the article and any adjectives must agree with it.

Spanish often omits subject pronouns when they are not needed, because the verb ending already tells you the person and number.

Here, the verb is permite, which is:

• third person singular
• from permitir

So Spanish does not need to say ella permite. The subject is already clear from the noun phrase la manguera.

In other words:

• La manguera permite... = The hose allows...
• Ella permite... would mean She/it allows..., but it would sound odd here because la manguera is already stated.

Permite is the third person singular present tense of permitir.

Basic meaning:

• permitir = to allow, to permit

In this sentence, though, it can also feel more like:

• makes it possible to
• enables

So La manguera permite regar el bancal is not saying the hose gives permission like a person would. It means the hose makes watering the garden bed possible.

That is a very natural use of permitir in Spanish.

Because permitir is normally followed directly by an infinitive when it means to allow doing something.

So:

• permite regar = allows watering / allows one to water

You do not put a before regar here.

A useful pattern is:

• permitir + infinitive

Examples:

• Esto permite ahorrar agua. = This allows you to save water.
• La llave permite abrir la puerta. = The key allows you to open the door.

You may see permitir a alguien + infinitive when the person is mentioned:

• La profesora permite a los alumnos salir.
  = The teacher allows the students to leave.

But in your sentence, no person is mentioned, so it is simply:

• permite regar

Because after permitir, Spanish often uses an infinitive to express the action that is allowed or made possible.

So the structure is:

• La manguera = the subject
• permite = the main verb
• regar el bancal = the action that the hose allows

In English, we often say:

• allows you to water the bed
• allows watering the bed

Spanish uses the infinitive more directly:

• permite regar

This is very common and natural.

Regar means to water in the sense of watering plants or land.

It is a stem-changing verb:

• e → ie in many present-tense forms

For example:

• yo riego
• tú riegas
• él/ella riega
• nosotros regamos
• vosotros regáis
• ellos riegan

But in the sentence you gave, it appears as the infinitive:

• regar

So there is no stem change visible there.

Also, do not confuse regar with:

• llover = to rain
• mojar = to make wet

Regar specifically means to water plants/soil.

In Spain, bancal usually refers to a cultivated plot, garden bed, or sometimes a terraced piece of land, depending on the region and context.

In a gardening context, it often means something like:

• garden bed
• vegetable bed
• raised bed
• sometimes simply plot

So in this sentence, el bancal is probably the area of soil where plants are being grown.

This word is somewhat more specific and regional than a very general word like jardín. A learner should know that bancal is a perfectly normal Spain Spanish word, especially in gardening or agriculture.

Because el means the, and here the sentence is most naturally referring to a specific garden bed that is already known from the context.

So:

• el bancal = the garden bed
• un bancal = a garden bed

Spanish often uses the definite article when both speaker and listener know which thing is being talked about.

For example, if you are already talking about a particular vegetable bed in the garden, then el bancal makes perfect sense.

Yes, that is a possible way to understand the idea in English.

Spanish often leaves the agent unspecified in structures like this. So permite regar el bancal can feel like:

• allows one to water the garden bed
• makes it possible to water the garden bed
• allows the garden bed to be watered

The sentence does not explicitly say who is doing the watering. It just says that the hose makes that action possible.

That vagueness is completely normal in Spanish.

Because Spanish grammar works differently here.

In English, we usually need:

• allows someone to water

But Spanish commonly says:

• permite regar

The infinitive regar already works as the complement of permite, so no extra word like English to is needed in the same way.

Remember that Spanish infinitives already end in:

• -ar
• -er
• -ir

So regar itself is the infinitive form, equivalent to to water.

Grammatically, it means allows. But in natural English, the idea may sometimes be closer to can or makes it possible to.

Compare:

• La manguera permite regar el bancal.
• Literal: The hose allows watering the garden bed.
• Natural: The hose lets you water the garden bed.
• Also natural: With the hose, you can water the garden bed.

So the core meaning is still permit/allow, but the practical meaning is often enable.

The g is pronounced differently depending on the vowel that follows it.

In these words:

• manguera: the gu before e gives a hard g sound
• regar: the g before a is also a hard g sound

So both have a sound similar to the g in get.

Very roughly:

• manguera ≈ man-GEH-ra
• regar ≈ reh-GAR

A useful spelling point:

• Before e or i, Spanish often uses gu to keep the hard g sound:
  • guerra
  • seguir
  • manguera

Without the u, ge and gi would sound very different.

Yes. This pattern is very common:

• noun + permitir + infinitive

It is used to say that something makes an action possible.

Examples:

• La aplicación permite reservar billetes.
  = The app allows you to book tickets.
• Esta puerta permite acceder al jardín.
  = This door allows access to the garden.
• La manguera permite regar el bancal.
  = The hose allows you to water the garden bed.

So this sentence is a very useful model to learn from.

Yes, but it is not exactly the same structure.

• La manguera permite regar el bancal.
  More general and impersonal: The hose allows watering the garden bed / allows one to water it.

• La manguera permite que riegues el bancal.
  More explicitly about you watering it: The hose allows you to water the garden bed.

A very important grammar point: after permitir que, Spanish normally uses the subjunctive:

• permite que riegues

So both are possible, but the original sentence is simpler and more general.

Yes, absolutely.

Depending on the tone, these can all work:

• The hose allows you to water the garden bed.
• The hose lets you water the garden bed.
• The hose makes it possible to water the garden bed.

Lets is often more natural in everyday English, while allows is a bit more neutral or formal. The Spanish sentence itself is perfectly normal and not especially formal.
