¿Puede explicar otra vez? — Can you explain again? Use this to ask for a new explanation, possibly simpler.

¿Qué significa esta palabra? — What does this word mean? A direct request useful for vocabulary gaps.

¿Puede decirlo más despacio? — Can you say it more slowly? Helpful when the speaker is too fast.

Here are real classroom examples using beginner-level Spanish so learners can see the phrases in context.

No entiendo esta parte. ¿Puede explicarla otra vez, por favor?

During a group activity when one instruction is unclear:

No comprendo el paso número tres. ¿Cómo lo hacemos?

If a written worksheet has a sentence you don’t get:

These examples show how to use the expressions outside class — at work, in a store, or reading signs and forms.

On a form: If a form field is unclear, say

No entiendo esta parte del formulario. ¿Qué debo escribir aquí?

At a café when a menu item is unclear:

No entiendo esta descripción. ¿Qué lleva este plato?

Useful vocabulary to memorize

Learning a few supporting words will make your requests clearer and more precise.

Frase — sentence or phrase

Oración — sentence (more formal/written)

Parte — part, section

Explicación — explanation

Ejercicio — exercise, task

Formulario — form

Documento — document

How to be specific: pointing out the exact part

Beginners will get better responses if they can point to the exact problem. Here are short patterns to combine with the key phrases.

No entiendo esta parte del párrafo — use when you refer to a portion of a paragraph.

No entiendo la tercera línea — use when a line in a text is unclear.

No entiendo la palabra marcada en rojo — useful for printed materials or PDFs.

No entiendo el verbo subrayado — use this when the problem is a verb form.

Politeness and tone: what to say and what not to say

Beginners sometimes worry about sounding rude. These tips help you ask for help politely and clearly.

Always add por favor at the end of requests to sound polite: ¿Puede repetir eso, por favor?

To show appreciation, add gracias after the person helps you: Gracias, ahora entiendo mejor.

Avoid blunt or negative forms like No sé nada — that sounds extreme and rarely true. Better: No entiendo esta parte.

Common mistakes beginners make

Awareness of typical errors will help you avoid them and communicate more effectively.

Using decir instead of explicar: Decir means to say; explain uses explicar. Instead of ¿Puede decirlo otra vez? say ¿Puede explicar otra vez? when you need clarification of meaning.

Mixing gender agreement: Remember esta parte (feminine). Do not say este parte. Use esta with parte.

Overusing entiendo for everything: Entiendo is fine, but comprendo is useful in formal or written contexts. Both are correct.

Forgetting verb conjugation: If you speak about someone else, change the verb: No entiende esta parte (He/She/You formal does not understand this part). For a group: No entendemos esta parte (We do not understand this part).

Quick practice exercises for beginners

Short drills help lock in the phrases. Practice aloud or write simple variations of these prompts.
