No quiero perder la esperanza.

Because Spanish often drops subject pronouns when the verb ending already makes the subject clear.

Here, quiero is the first-person singular form, so it already tells you the subject is I.

• No quiero perder la esperanza = normal, natural
• Yo no quiero perder la esperanza = possible, but more emphatic

You would add yo if you want contrast or emphasis, for example:

• Yo no quiero perder la esperanza, pero él sí.

Quiero is the present indicative, first-person singular form of querer.

So grammatically, it means:

• I want
• sometimes I love or I care for, depending on context

In this sentence, because it is followed by another verb, perder, it clearly means I want.

Compare:

• Quiero dormir. = I want to sleep.
• Quiero a mi familia. = I love my family.

After querer, Spanish normally uses an infinitive when the subject of both verbs is the same.

So:

• Quiero perder = I want to lose
• both actions belong to the same subject: I

This is a very common structure:

• Quiero comer.
• No quiero salir.
• Queremos aprender.

If the second action has a different subject, Spanish usually changes structure:

• No quiero que pierdas la esperanza. = I don’t want you to lose hope.

So:

• same subject → querer + infinitive
• different subject → querer que + subjunctive

In Spanish, no goes before the conjugated verb to make the sentence negative.

So:

• Quiero perder la esperanza. = affirmative
• No quiero perder la esperanza. = negative

Even though there is another verb afterward, no still goes before the main conjugated verb, which is quiero.

You see the same pattern in:

• No puedo ir.
• No voy a llamar.
• No quiero hablar.

There are two reasons:

1. Esperanza is a feminine noun, so its article is la.
2. In Spanish, abstract nouns often appear with an article where English would not use one.

Also, perder la esperanza is the normal idiomatic expression. It is the standard way to say to lose hope.

So although English says just hope, Spanish naturally says la esperanza here.

For a learner, it is best to remember the whole chunk:

• perder la esperanza

rather than trying to translate word by word.

Yes, it is a very common expression in Spanish. It works much like a set phrase meaning to lose hope.

That is why it sounds so natural in this sentence.

Some related expressions are:

• tener esperanza / tener esperanzas
• mantener la esperanza
• recuperar la esperanza
• no perder la esperanza

Learning it as a full phrase will help you use it more naturally.

Yes, but the nuance can be a little different.

• perder la esperanza = lose hope in a general sense
• perder las esperanzas = lose one’s hopes, often referring to specific hopes or expectations

In many contexts, both are possible, but perder la esperanza is the most neutral and standard version of the idea in your sentence.

So if you are unsure, No quiero perder la esperanza is the safest choice.

Then Spanish usually switches to que + subjunctive.

Your sentence uses the same subject for both verbs:

• No quiero perder la esperanza.
• I do not want to lose hope

But if you mean I don’t want you to lose hope, Spanish says:

• No quiero que pierdas la esperanza.

That is because the subjects are different:

• I don’t want
• you to lose hope

This is a very important pattern in Spanish:

• same subject → querer + infinitive
• different subject → querer que + subjunctive

The original order is the most natural and neutral one:

• No quiero perder la esperanza.

Spanish does allow word order changes for emphasis, but they are usually more marked and less beginner-friendly.

For example, you might hear something like:

• La esperanza no la quiero perder.

That puts extra emphasis on la esperanza, and it also needs the object pronoun la.

So yes, word order can change, but for normal use, stick with:

• No quiero perder la esperanza.

A rough pronunciation guide for Spain would be:

• no KYE-ro pehr-DER la es-pe-RAN-tha

A few useful points:

• qu in quiero sounds like k
• the u in que/qui is silent
• the r in perder is a light Spanish r, not a strong English r
• the z in esperanza is pronounced like th in think in most of Spain

Stress:

• QUIE-ro
• per-DER
• es-pe-RAN-za

So in most of Spain, esperanza sounds roughly like:

• es-pe-RAN-tha

It is very similar, but the tone changes.

• No quiero perder la esperanza = direct, straightforward
• No quisiera perder la esperanza = softer, more tentative, sometimes more formal or emotional

So both are correct, but quiero is the plain everyday version, while quisiera sounds a bit more delicate or reflective.

For most learners, the original sentence is the clearest and most neutral form.
