La sopa sigue caliente.

Sigue is the third-person singular form of seguir, which usually means to continue or to keep on.

In La sopa sigue caliente, it means something like:

• The soup continues hot
• more natural English: The soup is still hot

So Spanish often uses seguir + adjective to express still being in a state.

Examples:

• Sigue abierto = It’s still open.
• Sigo cansado = I’m still tired.
• Siguen aquí = They’re still here.

You can say La sopa está caliente, but it means simply:

• The soup is hot

That sentence does not emphasize that it remains hot.

Compare:

• La sopa está caliente = The soup is hot.
• La sopa sigue caliente = The soup is still hot / remains hot.

So sigue adds the idea of continuation.

Because caliente is an adjective with one form for both masculine and feminine singular nouns.

So you get:

• el café caliente
• la sopa caliente

Not all adjectives change to -a for feminine. Many adjectives ending in -e stay the same:

• interesante
• grande
• triste
• caliente

Only the article changes here: la sopa, not the adjective.

Yes. Spanish uses the definite article much more often than English.

So La sopa sigue caliente is completely natural even if English might sometimes say just:

• Soup is still hot in a very contextual situation

In normal Spanish, la sopa is the standard way to refer to the soup or the soup we’re talking about.

Without the article, Sopa sigue caliente, the sentence sounds wrong.

In Spanish, adjectives often come after the noun, especially when they describe a basic quality.

So:

• la sopa caliente = the hot soup
• el café frío = the cold coffee

This is the normal position for many descriptive adjectives.

In your sentence, caliente comes after sigue, because it is functioning as a predicate adjective:

• La sopa = subject
• sigue = verb
• caliente = adjective describing the subject

That structure is very common:

• El agua está fría
• La puerta sigue abierta

In sigue, the u is silent.

So sigue is pronounced roughly like:

• SEE-geh

not:

• SIG-oo-eh
• SEE-gway

This happens with gue and gui in many Spanish words, where the u is just there to keep the g hard:

• guerra
• guía (here the í changes things, and the u is pronounced because of the accent mark)
• sigue

A useful contrast:

• gue/gui → usually silent u
• güe/güi → pronounced u

For example:

• sigue → silent u
• pingüino → the u is pronounced

Because Spanish usually doesn’t need subject pronouns when the verb form already shows who or what the subject is, and when the noun is already stated.

Here, the subject is clearly La sopa, so adding a pronoun would be unnecessary.

• La sopa sigue caliente = normal
• Ella sigue caliente = would mean She is still hot, which is a completely different sentence

Spanish often omits pronouns unless they are needed for emphasis, contrast, or clarity.

Yes. Those are also correct.

Compare:

• La sopa sigue caliente = The soup is still hot / remains hot
• La sopa todavía está caliente = The soup is still hot
• La sopa aún está caliente = The soup is still hot

These are very similar, but there is a slight difference in feel:

• seguir + adjective focuses on the idea that the condition continues
• todavía/aún adds the adverb still

All are natural.
Sigue caliente is especially neat and idiomatic.

Good question. The verb seguir here does not replace the usual ser/estar distinction in the same way. Instead, seguir means to continue in a state.

The adjective caliente describes a state, and seguir tells us that this state continues.

So think of it like this:

• está caliente = it is hot
• sigue caliente = it continues to be hot

You do not need to insert está because seguir already works as the main verb in this structure.

Yes, very often. This is a very useful pattern.

Common examples:

• Sigue enfermo = He’s still ill.
• Sigo ocupado = I’m still busy.
• Seguimos listos = We’re still ready.
• La tienda sigue cerrada = The shop is still closed.

So seguir + adjective is a pattern worth learning as a whole, because it is extremely common in everyday Spanish.
