¿El oftalmólogo siempre dilata la pupila?

Questions & Answers about ¿El oftalmólogo siempre dilata la pupila?

What if I just want to say "The pupil dilates" without mentioning the ophthalmologist?
You would need to use the pronominal form of the verb, dilatarse, because the pupil is undergoing the change itself without a stated outside agent. The sentence would be La pupila se dilata. In our example sentence, dilatar is used transitively because the doctor is actively causing the dilation.
If I wanted to specifically ask if the doctor dilates my pupil or your pupil, would I use mi or tu pupila?
You would generally still use the definite article la pupila. In Spanish, body parts almost always take definite articles (el, la, los, las) rather than possessive adjectives. To clarify whose pupil is being dilated, Spanish uses an indirect object pronoun before the verb, such as ¿El oftalmólogo siempre te dilata la pupila? (Does the ophthalmologist always dilate your pupil?).
Is the word order strictly Subject-Adverb-Verb-Object in Spanish questions like this?
No, Spanish question word order is highly flexible. While this sentence uses a standard declarative order framed by question marks (¿El oftalmólogo siempre dilata...?), it is equally natural to place the subject at the end and ask, ¿Siempre dilata la pupila el oftalmólogo?
Why is there no "personal a" before la pupila?
Spanish only requires the "personal a" when the direct object is a specific person or a personalized pet. Since la pupila (the pupil) is a body part, it is treated grammatically as an inanimate object and directly follows the verb.
