Questions & Answers about Dudo que la masa madre haya fermentado hoy.
Why is haya fermentado (present perfect subjunctive) used here instead of a regular past tense?
The phrase Dudo que expresses uncertainty and forces the following verb into the subjunctive mood. Because the doubting happens right now in the present, but we are talking about an action that supposedly already happened earlier today, we need the present perfect subjunctive (haya fermentado). This translates directly to "has fermented".
What does masa madre literally translate to?
It literally means "mother dough." This is the standard Spanish term for a "sourdough starter" used in baking bread.
If I am completely certain the dough didn't ferment, can I use the indicative ha fermentado instead?
No. The verb dudar (to doubt) followed by que strictly requires the subjunctive mood in Spanish. Even if you firmly believe the dough hasn't fermented, the grammatical structure of expressing doubt still forces you to use haya fermentado.
How does the subjunctive in this sentence compare to the subjunctive used with a medida que in our current lesson?
While this sentence doesn't contain a temporal clause like a medida que (as/while), the underlying logic of the subjunctive is exactly the same. You use the subjunctive with a medida que for anticipated actions that aren't yet reality, and you use it with dudo que for actions whose reality you are questioning. In both cases, the subjunctive signals that the event is not being declared as an established fact.
