Questions & Answers about No causen más demoras, por favor.
Why does this sentence use causen instead of causan or causéis?
This is a negative command directed at a formal plural group (ustedes). All negative commands use the subjunctive mood, which changes the -a- vowel in causar to an -e-. If you were addressing a group informally in Spain (vosotros), you would use the informal negative command no causéis.
Is demora used differently from retraso?
Both words mean delay and are largely interchangeable. However, demora often sounds a bit more formal, administrative, or technical (like flight delays or bureaucratic hold-ups), which perfectly matches the formal ustedes register of this sentence. Retraso is the standard go-to word in everyday conversation.
How could I rephrase this sentence to say 'There must not be more delays', using a periphrasis with haber from this lesson?
You would say No debe haber más demoras. Applying the rule from this lesson, the periphrasis debe haber remains in the third-person singular even though demoras is plural. A common mistake among natives and learners alike is to pluralize it to no deben haber, but impersonal haber never changes to match the plural noun.
