In both formal (Ud.) and informal (tú) negative commands in Spanish, the placement of the indirect object pronoun and the direct object pronoun differs.
For affirmative commands:
- In informal commands (tú), the pronouns are attached to the end of the verb in affirmative commands.
- In formal commands (Ud.), the pronouns are placed before the verb.
However, in negative commands:
- Both informal (tú) and formal (Ud.) negative commands require the placement of the indirect object pronoun and the direct object pronoun before the verb.
So, the statement "In both Ud. and tú negative commands, the indirect object pronoun and the direct object pronoun always precede the verb" is **True**.
