El precio parece ridículo.

In Spanish, the definite article is used more often than in English. El precio means the price, and Spanish normally includes the article when talking about a specific thing or concept in a sentence like this.

So Spanish prefers:

El precio parece ridículo.

rather than:

Precio parece ridículo. ❌

Leaving out the article here sounds incomplete or unnatural.

Parecer means to seem or to look. So parece ridículo suggests an appearance, impression, or opinion:

• Parece ridículo = it seems ridiculous
• Es ridículo = it is ridiculous

Using parece can sound a bit softer or less absolute than es. A speaker may be saying that the price gives that impression, rather than making a completely direct statement.

Because the subject is el precio, which is singular.

• el precio = singular
• parece = 3rd person singular

If the subject were plural, you would use parecen:

• Los precios parecen ridículos.

So the verb has to agree with the noun it refers to.

Because it agrees with precio, which is a masculine singular noun.

Agreement in Spanish affects adjectives:

• el precio ridículo / parece ridículo → masculine singular
• la oferta ridícula → feminine singular
• los precios ridículos → masculine plural
• las tarifas ridículas → feminine plural

Even though in English ridiculous never changes form, in Spanish the adjective must match the noun.

Here, ridículo is not directly modifying the noun inside a noun phrase. It is working as a predicate adjective after the verb parecer.

Structure:

• El precio = subject
• parece = verb
• ridículo = adjective describing the subject after the verb

This is similar to English:

• The price seems ridiculous.

If you put the adjective directly with the noun, you get a different structure:

• el precio ridículo = the ridiculous price

Both are correct, but they do different jobs.

Usually yes, but it is worth knowing the nuance. In this sentence, ridículo means something like:

• absurd
• unreasonable
• laughably high/low
• outrageous

With prices, it often means the speaker thinks the amount is extreme or unjustifiable.

It does not necessarily mean funny in a cheerful way. It often sounds critical.

The written accent in ridículo shows the stress: ri-DÍ-cu-lo.

Without the accent, Spanish pronunciation rules would place the stress differently, so the accent mark is necessary.

This is very common in Spanish: accent marks are often used to show where the stress goes when a word does not follow the default stress pattern.

In Spain, precio is usually pronounced approximately like:

PRE-thyo in much of Spain

because the c before i is often pronounced like the th in thin.

In Latin America, it is usually pronounced more like:

PRE-syo

Both are correct in their own varieties of Spanish. Since you asked about Spain, the Castilian pronunciation with th is the expected one.

Yes. That is perfectly grammatical, but the nuance changes slightly.

• El precio parece ridículo. = The price seems ridiculous.
• El precio es ridículo. = The price is ridiculous.

The version with es is more direct and stronger. The version with parece sounds a bit more observational or subjective.

Yes. This is a very common pattern.

Parecer + adjective means to seem + adjective:

• Parece fácil.
• Parece imposible.
• El plan parece bueno.
• El precio parece ridículo.

You can also use parecer + noun or longer structures, but parecer + adjective is one of the most basic and useful patterns to learn.
