Learn Spanish (Latin America): El pintor dejó el zócalo blanco embarrado. - The painter left the white baseboard smeared.

This sentence uses the resultative state structure dejar plus a past participle (embarrado). It emphasizes the physical state that the painter's actions caused. Instead of just stating the action he performed, it focuses on the messy result he left behind.

Why is embarrado separated from dejó by the object?

In this structure, the direct object (el zócalo blanco) usually goes between dejar and the past participle. You are literally saying that the subject left the object in a specific state.

Embarrado usually means 'muddy'. Why is it translated as 'smeared' here?

While barro means mud, embarrado is broadly used in Latin America to describe something smeared, splattered, or dirtied with any thick, paste-like substance. In the context of a painter, it implies he carelessly left the baseboard smeared with paint, plaster, or spackle.

Since there are two adjectives (blanco and embarrado), why don't we put an y (and) between them?

Because they aren't a list of equal adjectives modifying the noun. El zócalo blanco is the complete direct object (the white baseboard). Embarrado describes the resultative state linked to the verb dejó. Adding y would incorrectly change the grammar, making it sound like he left the baseboard both white and smeared.
