I don't know spanish

pedir means order or ask, it can be used in a present tense or past tense way and can be used in a first person pov or second person pov. (thats how its most commonly used) Nosotros is a term that means you and I. Which means who ever is talking and who ever they are talking to take part. The word pedimos has mos at the end, which is mostly used to represent multiple people like nosotros. Pedimos means we ask. You and I ask. Its a mix of ask and us, like pedir and nosotros. This can also be used in any point of view. Also in any time, like past, present, future. Whatever has "mos" or "os" at the end means "we".  Reír means laugh. Since reimos has "mos" at the end, that means we, so it means "We laugh". Its a mix again. Vosotros means "you" or in some cases "you guys". Since it has "os" you can tell its in a certain point of view. In this case, it is in the second person or in other words second hand point of view. This can also be used when talking about any time, whether it be the past present or future. Pedís means "you ask". This can be said in second person pov and mainly in the present tense. Reís means "you laugh". You can see there is another pattern, when a word has "ís" at the end, it is second person pov.
