[Hay que + Infinitive]: The Impersonal Obligation Chunk

The Chunk: Hay que + [infinitive]

Hay que + infinitive expresses impersonal obligation – what one must do, what has to be done in general. There's no specific subject: it applies to everyone, or to no one in particular.

The form never changes. Hay is invariable – it doesn't conjugate for person. You just add que and the infinitive of whatever needs doing. That's the whole chunk.

Why This Chunk Is Critical

• Very high frequency: You'll hear hay que constantly – in rules, advice, signage, proverbs, and everyday conversation.
• Impersonal angle: It lets you state obligations that apply to everyone, without pointing at anyone specifically. Perfect for advice, rules, and general truths.
• Lowest possible processing load: One form, always. No conjugation to remember.
