So we've covered how to say the I/she/he/it/you (formal) versions of verbs when talking about a point (dot) in the past, Now we'll learn the 'we' form - 'We spoke', 'we ate', etc.
Remember we still are talking about that 'dot' in the past - how the past tense looks when we refer to a specific moment in the past (e.g. "I rode my bicycle yesterday") rather than making a general statement about something which happened over a period of time - e.g. "I used to ride my bicycle in the countryside".
Now the we form is slightly wierd for 'ar verbs!
|  Spanish |  English | 
|---|---|
| Hablamos | We speak | 
| Hablamos | We spoke | 
Yes - they are exactly the same! No typo there. This can cause confusion even amoung native Spanish speakers so naturally they use several tools to repair this very natural flaw.
|  Spanish |  English | 
|---|---|
| Cuando hablamos comprendo todo | When we speak I understand everything | 
| Cuando hablamos comprendí todo | When we spoke I understood everything | 
| Hablamos ayer | We spoke yesterday | 
| Hablamos mañana | We will speak tomorrow | 
So we see here that even to get the future tense we can use 'hablamos' as long as we put some future context in the sentence like "tomorrow".
|  Spanish |  English | 
|---|---|
| Esperamos mucho | We wait a lot | 
| Esperamos mucho ayer | We waited a lot yesterday | 
'er' verbs do change slightly for the past tense
|  Spanish |  English | 
|---|---|
| Comemos | We eat | 
| Comimos | We ate | 
| No comimos | We didn't eat | 
| Vemos | We see | 
| Vimos | We saw | 
| Perdemos | We lose | 
| Perdimos | We lost | 
| Nos perdimos | We got lost | 
| Nos perdemos siempre pero no nos perdimos ayer | We always get lost but we didn't get lost yesterday | 
... but 'ir' verbs are like 'ar' verbs, on their own you can't tell them apart.
|  Spanish |  English | 
|---|---|
| Vivimos | We live | 
| Vivimos | We lived | 
| Salimos | We're going out / leaving | 
| Salimos | We went out / left | 
| No salimos a menudo pero salimos ayer | We don't go out often but we went out yesterday |
