What does it mean word for word?
The phrase por qué literally breaks down to por (for/by) and qué (what/which).
Which one should you use?
The interrogative por qué is used to ask "why", whereas the single word porqué is a noun meaning "the reason". Additionally, do not confuse the question "why" with porque, which means "because" and is written as one word without an accent.

- In some Spanish dialects, asking ¿Por qué? repeatedly in a sharp tone can be interpreted as a challenge to authority rather than a genuine request for information.
- The phrase a son de qué contains the word son, which shares a root with the English word 'sound'. It refers to the tone or manner of an action.
- In casual speech, Spanish speakers may omit ¿Por qué? entirely and use a rising intonation on a statement to imply a 'why' question.
