Question

choose the best informal spanish tú translation of the following sentence.

be good.

sé bueno.
ser bueno.
eres bueno.
seas bueno.

Explanation:

Identify the target grammatical structure

The English sentence "Be good" is an affirmative command addressed informally to one person (tú).

Analyze the verb and its conjugation

The verb "to be" in this context refers to a personal characteristic, which requires the Spanish verb ser. The affirmative informal (tú) command form of the irregular verb ser is sé.

Evaluate the given options

• "Sé bueno." uses the correct affirmative tú command form sé.
• "Ser bueno." uses the infinitive form ser, which is incorrect for a direct command.
• "Eres bueno." uses the present indicative form, meaning "You are good," rather than a command.
• "Seas bueno." uses the present subjunctive form, which is used for negative commands (e.g., "No seas...") but not affirmative ones.

Answer:

• Sé bueno. (Correct answer)
• Ser bueno.
• Eres bueno.
• Seas bueno.
