Regamos la parcela con la manguera.

Regamos is the first-person plural form of regar: we water / we irrigate.

A very important point: regamos can mean either:

• present: we water
• simple past (preterite): we watered

The form is identical in both tenses for nosotros. Only context tells you which one is meant:

• Cada tarde regamos la parcela = We water the plot every afternoon
• Ayer regamos la parcela = We watered the plot yesterday

Spanish often leaves out subject pronouns because the verb ending already shows who is doing the action.

Here, -amos tells you the subject is we. So Regamos la parcela con la manguera is completely natural.

You could add nosotros for emphasis or contrast:

• Nosotros regamos la parcela, no ellos = We water the plot, not them

Because la parcela is a thing/place, not a person.

The so-called personal a is mainly used with specific people and sometimes animals:

• Veo a María
• Llamamos al perro

But with an inanimate direct object, you normally do not use a:

• Regamos la parcela
• Compramos la manguera

So la parcela is simply the direct object of regar.

Parcela usually means a plot of land, small piece of land, or allotment/parcel depending on context.

It often sounds more like a defined section of land than a general word like:

• terreno = land/ground
• campo = countryside/field
• jardín = garden

So la parcela suggests a specific plot, often for farming, gardening, or cultivation.

Because con is the normal way to express the instrument or means used to do something.

So:

• con la manguera = with the hose

This is the most natural structure in Spanish for this idea. You could also say usando la manguera (using the hose), but that usually sounds heavier and less natural than simple con.

Spanish often uses the definite article where English might use a, the, or even a possessive, especially when the object is understood from the situation.

So con la manguera is very natural even if English might say with a hose.

Both are possible in Spanish, but they can feel slightly different:

• con la manguera = with the hose / with the hose we have in mind
• con una manguera = with a hose / with some hose, not necessarily a specific one

In everyday speech, con la manguera is very common.

You can tell from the article la:

• la parcela
• la manguera

Also, many Spanish nouns ending in -a are feminine, though that is not an absolute rule. The most reliable clue is the article used with the noun.

Because they are feminine singular nouns, they take la, not el.

The given order is the most neutral and natural one:

• Regamos la parcela con la manguera

But Spanish word order is fairly flexible, especially for emphasis. For example:

• Con la manguera regamos la parcela = emphasizes the tool
• La parcela la regamos con la manguera = emphasizes the plot

So yes, the order can change, but the original version is the standard, neutral way to say it.

Yes. Regar can be used with:

• plants: regar las plantas
• a garden: regar el jardín
• grass/lawn: regar el césped
• land/plots/fields: regar la parcela, regar el campo

So in this sentence, using regar with parcela is completely normal.

In standard Spanish (including Spain), manguera is pronounced roughly like:

man-GEH-ra

A useful spelling point: in gue, the u is silent unless it has a diaeresis (ü). So:

• manguera = the g stays hard, like in go
• the u is not pronounced separately

Also, the r in -ra is a single Spanish r, not the strong rolled rr sound.
