Learn Spanish (Latin America): Si te equivocas, me lo tienes que destejer. - If you make a mistake, you have to unravel it for me.

Both options are perfectly fine! When you have a conjugated verb followed by an infinitive (like tienes que destejer), you can place the object pronouns before the conjugated verb (me lo tienes que destejer) or attach them to the end of the infinitive (tienes que destejérmelo). Placing them before the conjugated verb is very common in everyday speech.

Why is there a te before equivocas?

The verb for 'to make a mistake' or 'to be wrong' is the pronominal verb equivocarse. The te is the pronoun that matches the tú subject. Without the pronoun, equivocar means 'to confuse' someone or something else.

What exactly do me and lo represent in this sentence?

lo is the direct object pronoun, referring to the masculine object that was made by mistake (like a sweater or a project) and needs to be unraveled. me is the indirect object pronoun, meaning 'for me' or 'to me', indicating who is affected by the unraveling or who requested it.

Is destejer related to the word for knitting or weaving?
