Questions & Answers about Yo le expliqué que esa tecla controla el volumen del altavoz.
What is the function of the pronoun le?
le is the third-person (or formal second-person) indirect object pronoun. It tells you “to whom” the action is directed—“I explained to him/her/you (formal).” Spanish requires this pronoun even if you don’t explicitly name the person.
Why does this sentence include Yo? Is it necessary?
Yo is the subject pronoun “I.” Since Spanish verb endings already identify the subject, Yo is optional and often omitted in everyday speech. Here it’s included for emphasis or contrast (“I explained, not someone else”). You could simply say Le expliqué que….
How does the conjunction que work here? Why not porque?
In this context, que introduces a content clause that reports what was explained (“that this key controls the volume”), just like English “that.” porque means “because” and introduces a reason, so replacing que with porque would change the meaning entirely and sound odd.
Why is esa used instead of esta or aquella?
esa is a demonstrative adjective meaning “that” (something not immediately next to the speaker but not very far either).
- esta = “this” (very close to the speaker)
- aquella = “that over there” (far from both speaker and listener)
What does tecla mean? How is it different from botón?
tecla literally means “key,” as on a keyboard, piano or control panel. botón is a more general word for “button” (e.g. a doorbell or app button). On many electronics you’ll hear both, but tecla emphasizes an individual key-style control.
Why is controla in the present tense when expliqué is in the past?
The main verb expliqué is past (“I explained”), but the subordinate clause states a permanent or habitual fact: that key’s function. Spanish (like English) uses the present tense to express general truths: “that key controls the volume.”
What does altavoz mean, and are there regional synonyms?
altavoz means “loudspeaker” or “speaker.” In Latin America you might also hear bocina or parlante, but altavoz is widely understood across all Spanish-speaking regions.
Why does tecla take a feminine demonstrative (esa)?
Nouns ending in -a are typically feminine in Spanish. Since tecla ends in -a, all accompanying articles, adjectives and demonstratives must be feminine—hence esa tecla.

“How does verb conjugation work in Spanish?”
Spanish verbs change form based on the subject, tense, and mood. Regular verbs follow predictable patterns depending on whether they end in ‑ar, ‑er, or ‑ir. For example, "hablar" (to speak) becomes "hablo" (I speak), "hablas" (you speak), and "habla" (he/she speaks) in the present tense.
