guíes

Guíes is the second-person singular present subjunctive form of the Spanish verb guiar, corresponding to tu guíes. It is used in subordinate clauses that express doubt, desire, possibility, necessity, or hypothetical situations. The present subjunctive forms of guiar are: yo guíe, tú guíes, él/ella guíe, nosotros guiemos, vosotros guiéis, ellos guíen.

Guíes should not be confused with guías, which is the plural of the noun guía (guide). The noun guía means a person who leads or a manual/directory, and its plural guías carries an accent on í. Guíes, in contrast, is a verb form and not a noun. The accent in guíes helps indicate the subjunctive mood and correct pronunciation.

Usage and examples illustrate its function in contexts of uncertainty, desire, or instruction within a clause. Examples include: Es probable que tú guíes al grupo. Quiero que tú guíes a los recién llegados. Espero que tú guíes el camino con cuidado. Note that the corresponding formal second-person singular subjunctive for usted is guíe, not guíes.

In summary, guíes is a verb form used to express a hypothetical or non-assertive action by the informal you in Spanish, while guías (noun) refers to guides. Understanding the distinction hinges on context, accent marks, and the grammatical mood of the sentence.
