En el parque vimos una mariposa amarilla cerca del estanque.

Spanish usually needs the definite article with many place nouns when talking about a specific, known place. So en el parque means in the park.

Unlike English, Spanish often uses articles more regularly:

• en el parque = in the park
• en la casa = in the house
• fuimos al cine = we went to the cinema

Leaving out el here would sound ungrammatical.

Because de + el contracts to del in Spanish.

So:

• de + el = del
• a + el = al

That is why you get:

• cerca del estanque = near the pond
• al parque = to the park

Important exception: if El is part of a proper name, you do not contract it:

• de El Escorial (not del Escorial when referring to the official name)

Vimos is the preterite form of ver (to see), for nosotros/nosotras (we).

So:

• vi = I saw
• viste = you saw
• vio = he/she saw
• vimos = we saw
• visteis = you all saw
• vieron = they saw

The preterite is used for a completed action in the past. Here, vimos means we saw as a finished event.

Because Spanish often leaves out subject pronouns when the verb already shows who is doing the action.

In vimos, the ending -mos tells you the subject is we. So nosotros is unnecessary unless you want emphasis or contrast.

Compare:

• Vimos una mariposa. = We saw a butterfly.
• Nosotros vimos una mariposa. = We saw a butterfly. (more emphatic, maybe contrasting with someone else)

This is very common in Spanish.

In Spanish, adjectives usually come after the noun.

So:

• una mariposa amarilla = a yellow butterfly
• una casa grande = a big house
• un coche rojo = a red car

Putting the adjective before the noun is possible in some cases, but it often changes the tone, style, or meaning. For a simple descriptive color adjective, the normal order is noun + adjective.

Because adjectives in Spanish usually agree with the noun in gender and number.

Mariposa is feminine singular, so the adjective must also be feminine singular:

• mariposa amarilla = feminine singular
• mariposas amarillas = feminine plural
• pájaro amarillo = masculine singular
• pájaros amarillos = masculine plural

This agreement is one of the biggest differences from English.

One clue is that it ends in -a, which often suggests a feminine noun. That is why it takes:

• una mariposa
• la mariposa
• mariposa amarilla

But remember: endings are only a clue, not a perfect rule. Many nouns must simply be learned with their article:

• la mariposa
• el problema
• la mano

A good habit is to learn nouns together with el or la.

Because cerca normally works with the preposition de when saying what something is near.

So:

• cerca del estanque = near the pond
• cerca de la casa = near the house
• cerca de mí = near me

This is just the standard pattern:

• cerca de
• lejos de

You should learn cerca de as a fixed expression.

Actually, this sentence is quite close to normal English order:

• En el parque = In the park
• vimos = we saw
• una mariposa amarilla = a yellow butterfly
• cerca del estanque = near the pond

Spanish is often flexible with word order, but this sentence uses a very natural structure:

1. place
2. verb
3. object
4. extra location detail

You could also say:

• Vimos una mariposa amarilla en el parque, cerca del estanque.

That sounds natural too. Spanish often moves place phrases around more freely than English.

Not with exactly the same meaning.

• ver = to see
• mirar = to look at

So:

• vimos una mariposa = we saw a butterfly
• miramos una mariposa = we looked at a butterfly

Vimos focuses on perception: the butterfly came into view. Miramos focuses on directing your eyes at it.

English sometimes uses see and look at the same way, and Spanish makes that distinction too.

Yes. In Spain, estanque is a normal word for a pond or ornamental body of still water, especially in a park or garden.

It suggests a smaller, contained body of water rather than a large natural lake.

Related words:

• estanque = pond
• lago = lake
• charca = puddle/small muddy pool
• fuente = fountain

So cerca del estanque fits very naturally with en el parque.

Because mariposa is a singular countable noun, and here it is being introduced as a butterfly, not the butterfly.

So:

• una mariposa = a butterfly
• la mariposa = the butterfly

Also, una must agree with the feminine noun:

• un pájaro = a bird
• una mariposa = a butterfly

Spanish articles show both number and gender, unlike English a/the.

In standard Spain Spanish:

• vimos sounds roughly like BEE-mos
• amarilla sounds roughly like a-ma-REE-ya in many parts of Spain

A few notes:

• Spanish v and b are pronounced very similarly.
• The ll in much of Spain is pronounced like y.
• Stress usually falls on the second-to-last syllable if the word ends in a vowel, n, or s, so:
  • VI-mos
  • a-ma-RI-lla
  • es-TAN-que

These English-style hints are only approximations, but they help with the basic sound pattern.
