✦Grammar Breakdown
Úsalossinproblema
Affirmative Imperative
For -ar verbs, the tú form drops the final -r and adds -a (usar → usa).
Enclitic Pronoun
In affirmative commands, object pronouns are attached to the end of the verb (usa + los → úsalos).
Accent Rule
When a pronoun is attached, the original stress may shift; an accent is added to preserve the original pronunciation (úsa‑).
Preposition sin
‘Sin’ means ‘without’ and is followed by a noun without an article.

✕Common Mistakes
Usalos sin problema.
Missing accent on the first vowel; the correct form is Úsalos to keep the original stress.
Úsalos sin problemas.
The idiomatic expression uses the singular ‘problema’. ‘Sin problemas’ sounds like ‘without problems’ and is less natural here.
No los úsalos.
In negative commands the pronoun precedes the verb: ‘No los uses’. Attaching it after the verb is only for affirmative commands.

Cultural Tip
In Spanish, the affirmative tú‑imperative attaches object pronouns to the verb (e.g., ‘úsalos’). For negative commands the pronoun goes before the verb (e.g., ‘No los uses’). Also, avoid the plural ‘sin problemas’ unless you’re referring to multiple issues; the singular ‘sin problema’ is the idiomatic way to say ‘no problem’.
