Questions & Answers about El escarabajo vuela cuando tiene alas.
Why is tiene used instead of the subjunctive tenga after cuando?
In time clauses starting with words like cuando (when), we use the indicative mood (tiene) to state facts, general truths, or habitual actions. Because a beetle flying when it has wings is a general biological fact, the indicative is used. We only use the subjunctive to talk about specific, uncompleted future events.
How would the meaning change if the sentence said cuando tenga alas?
Using the subjunctive tenga changes the meaning from a general fact to a future event. Cuando tenga alas means "when it gets wings (in the future)." You would use this if you were looking at a baby insect that hasn't grown wings yet, usually paired with a future tense verb: El escarabajo volará cuando tenga alas (The beetle will fly when it gets wings).
Why does the verb volar (to fly) become vuela here?
The verb volar is a stem-changing verb in the present tense. The o in the root changes to ue for all forms except nosotros and vosotros. This is why it becomes vuela for the beetle (it), just like poder becomes puede.
Why is there no subject pronoun like él before tiene?
In Spanish, subject pronouns are usually dropped when the context makes it clear who or what is performing the action. Since we just established that we are talking about el escarabajo (the beetle) in the first half of the sentence, adding él before tiene is unnecessary and would sound repetitive.
