Qué (interrogative pronoun)

parece (present of parecer)
Third‑person singular of the verb 'parecer' meaning 'to seem'; used here to express an observation or hypothesis.
ser (infinitive after parecer)

el (definite article)
Introduces a specific noun; agrees in gender and number with 'problema'.
problema (masculine noun)

Cultural Tip
In Spanish‑speaking workplaces, phrasing a question with 'parece ser' softens the inquiry, making it sound less confrontational. It signals that you are open to other interpretations and invites collaborative problem‑solving. Avoid using a very direct tone like '¿Cuál es el problema?' unless the context is informal or you have authority to demand an answer.
