"Tú serás una buena madre."
Translation:You will be a good mother.
The 'you' part of the verb in the English future is 'will' rather than 'shall'.
This is the first time I've seen "buena" before the noun. I was under the impression that "buen" precedes the noun, and buena/bueno come after the noun. Could someone knowledgeable elaborate on this for me? Muchas gracias.
