Temen otro terremoto.

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

Here, temen is a third-person plural verb form, so it can mean:

• they fear
• you all fear (formal plural ustedes)

So Temen otro terremoto naturally means They fear another earthquake unless the context shows it means you all.

Temen comes from the verb temer, which means to fear.

It is a regular -er verb:

• temo = I fear
• temes = you fear
• teme = he/she fears
• tememos = we fear
• teméis = you all fear (informal plural, mainly Spain)
• temen = they fear / you all fear

It is the present simple (also called the present indicative).

So temen means they fear or sometimes they are afraid of, depending on context.

In a sentence like this, English often translates it naturally as:

• They fear another earthquake
• They are afraid of another earthquake

In Spanish, otro normally goes directly before the noun without un.

So you say:

• otro terremoto = another earthquake

Not:

• un otro terremoto ❌

This is a very common pattern:

• otra vez = another time / again
• otro día = another day
• otra persona = another person

Because terremoto is a masculine singular noun.

Otro has to agree with the noun:

• otro terremoto = another earthquake
• otra tormenta = another storm

So the ending changes to match the gender and number of the noun.

Yes. Grammatically, temen can refer to:

• ellos/ellas = they
• ustedes = you all

In Spain, ustedes is usually used for formal plural you, while vosotros is used for informal you all.

So in Spain:

• vosotros teméis = you all fear (informal)
• ustedes temen = you all fear (formal)
• ellos/ellas temen = they fear

Without context, they fear is often the most likely reading.

Yes. Temer can take a direct object directly, so temer algo means to fear something.

Examples:

• Temen otro terremoto. = They fear another earthquake.
• Temo el fracaso. = I fear failure.
• Temen una crisis. = They fear a crisis.

So there is no need for a preposition like de here.

Yes, but Temen otro terremoto is the most neutral and natural order.

Spanish usually follows this pattern:

• verb + object in a sentence like this

You could change the order for emphasis, but it would sound less neutral:

• Otro terremoto temen. = marked/emphatic, not the usual choice

So for normal everyday Spanish, Temen otro terremoto is the best form.

It is pronounced roughly like te-rre-MO-to.

A few useful points:

• The stress falls on mo: terreMOto
• The rr in terremoto is a strong rolled or trilled r
• The e and o are pure Spanish vowels, shorter and clearer than in English

So the full sentence sounds approximately like:

TE-men O-tro te-rre-MO-to

Yes, in natural English that can be a good translation depending on context.

The core meaning of temer is to fear, but English often uses smoother phrases such as:

• They fear another earthquake
• They are afraid of another earthquake
• They are worried about another earthquake

The exact English version depends on the tone of the situation, but the Spanish structure stays the same.
