Questions & Answers about Ellos se reunieron ayer para ir al concierto.
Does the word ayer force the verb to be in a specific past tense?
Yes! Because ayer (yesterday) refers to a specific, completed timeframe, it is a huge clue to use the preterite tense (se reunieron). When you see expressions of past time like ayer or anoche (last night), you will almost always use the preterite rather than the imperfect tense.
Why is there a se before reunieron?
The verb here is reunirse (to get together / to meet up), so se is the reflexive pronoun for 'they'. It shows that they are getting together with each other. Without the se, reunir just means 'to gather' or 'to collect' something else, like gathering documents or collecting money.
Could I use por instead of para here?
No, you need para. When you want to express the purpose of an action or say 'in order to' do something, you always use para followed by an unconjugated verb (an infinitive). So, para ir translates directly to 'in order to go'.
Why does it say al concierto instead of a el concierto?
