Questions & Answers about Cuando hablo demasiado, paro y bebo agua.
Why is hablo (indicative) used after cuando instead of the subjunctive hable?
Because the sentence describes a habitual action (“whenever I speak too much…”). In Spanish, cuando + indicative is used for repeated or general truths. You would use the subjunctive (e.g. Cuando hable) only for a single, future, or uncertain event that hasn’t happened yet.
Could I say Cuando estoy hablando demasiado instead of Cuando hablo demasiado?
Why is demasiado placed after hablo, and why doesn’t it change ending?
Is the comma after demasiado necessary?
The comma separates the subordinate time clause (Cuando hablo demasiado) from the main clause (paro y bebo agua). In a short sentence it’s optional, but it helps signal the clause boundary and improves readability.
