English Translation
They are good people.
Why son? I thought gente is singular
They are good people.
Why son? I thought gente is singular
‘Son’ agrees with the ellided subject. ‘(Ellos/ellas) son buena gente’.
The attribute usually agrees with the subject, but this isn’t required. It’s a common pattern with collective (singular) nouns, like ‘sois un montón’, but it can happen with regular nouns as well. ‘Tus amigos son un estorbo’. ‘Los manifestantes parecen una ola’. When it goes the other way you can use the singular or the plural. ‘Este teléfono es tres dispositivos en uno’. ‘Un equipo de fútbol son once jugadores’.
