"They will pay."
Translation:Elas vão pagar.
Could be 'eles pagarão' but not 'eles vão pagam'. 'pagam' is present tense to 'they'
Yes, 'they are going to pay'
Which one is more common and is there a real difference in meaning:
- Elas vão pagar.
- Elas irão pagar.
According to grammar rules, only the first version is correct. You should use the present tense of "ir" to express future actions.
I asked because some of the multiple choice options presented had "irão" in them with a different infinitive verb. I thought it was just a variant with the same meaning. Obrigado =)
Actually, people use "ir" in future tense to express future. It's becoming common, but still not a standard, so we should avoid it. I work with languages, and it is considered wrong among reviewers and linguists.
