Questions & Answers about Nunca invertimos durante una crisis.
Does the verb invertimos stem-change here? I thought invertir was a stem-changing verb.
You are right that invertir is a stem-changing verb (specifically, changing the 'e' to 'ie' in the present tense, like invierto and inviertes). However, the nosotros form never stem-changes in the present indicative, which is why it remains invertimos.
Isn't invertimos also the past tense (preterite) form? How do we know this is present tense?
Yes, invertimos is identical in both the present and preterite tenses! The context usually gives it away. Here, using Nunca to state a broad habit strongly implies the present tense. If it were past tense referring to a specific historical event, you'd likely see time markers instead, such as Nunca invertimos durante la crisis de 2008.
If I move nunca to the end of the sentence, do I need to add a no?
The word crisis ends in an 's'. Does that mean it is plural?
