Here's the breakdown:
* escribe: means "write" in Spanish.
* con: means "with" in Spanish.
* eme mayúscula: refers to the letter "E" written in uppercase (capital).
* I: refers to the letter "I" in lowercase.
* te: is a conjunction, indicating a change in direction ("and then").
* zeta: refers to the letter "Z" in lowercase.
Therefore, the phrase is a silly instruction to write the letters "E", "I", and "Z" in that specific order. This is likely a game or a challenge of some sort.
