Mesoclisis: Pronouns

Mesoclisis only works with two specific verb tenses. These are the Futuro do Presente (Simple Future) and the Futuro do Pretérito (Conditional). If you are using the past or the present, forget about mesoclisis. It simply does not exist there. The pronoun literally interrupts the verb before it finishes. Imagine the verb is a train. The pronoun is a new car coupled right in the middle. This only happens when you cannot put the pronoun before the verb. In Portuguese, we usually prefer Próclise (pronoun before). But if the sentence starts with a verb in the future, mesoclisis is the formal rule. It prevents the pronoun from hanging off the front like an awkward hood ornament. It keeps the sentence balanced and traditional.

1. 1Building a mesoclisis sandwich follows a strict four-step recipe. Let's use the verb falar (to speak) and the pronoun te (you).
2. 2Start with the infinitive form of the verb: falar.
3. 3Identify the future or conditional ending: -ei (future) or -ia (conditional).
4. 4Place the pronoun after the infinitive: falar-te.
5. 5Attach the ending after the pronoun: falar-te-ei.
6. 6Notice the hyphens. You need two of them. One connects the verb to the pronoun. The other connects the pronoun to the ending. If the verb ends in r, s, or z, and the pronoun is o, a, os, or as, the rules change slightly. The r drops, and the pronoun becomes lo or la. For example, dar + o + ei becomes dá-lo-ei. It sounds like a tongue twister, but it follows a logical rhythm once you practice.

Use mesoclisis when you start a sentence with a verb in the future or conditional. This is the most common scenario for this pattern. Imagine you are writing a formal email to a CEO. You want to say, "I will give you the details." Instead of the casual Te darei, you use Dar-te-ei. It shows immense respect and education. You will also use it in academic writing. If you are defending a thesis, mesoclisis adds weight to your arguments. In legal contexts, lawyers use it to sound authoritative. It is also found in the Bible and classic literature. If you are reading Machado de Assis, you will see it everywhere. It is the language of the elite and the educated. Think of it as a tool for your professional toolkit. It is for when you need to be your most impressive self.

This is the most important part. Mesoclisis is easily scared away by "magnetic words." These are words that pull the pronoun to the front of the verb (Proclisis). If you have a negative word like não, nunca, or jamais, mesoclisis dies. You must say Não te falarei, never Não falar-te-ei. Relative pronouns like que also kill mesoclisis. If you say "The book that I will give you," it is O livro que te darei. Indefinite pronouns like alguém or todos also act as magnets. Adverbs like hoje or sempre do the same. Basically, if there is any strong word before the verb, the pronoun moves to the front. Mesoclisis only survives when the verb is the very first thing in the sentence or clause. It is a lonely grammar rule that hates company.

The biggest mistake is using mesoclisis in casual conversation. If you say Dar-te-ei um beijo to your partner, they might think you've turned into a 19th-century ghost. It is too stiff for the dinner table. Another mistake is using it with the wrong tenses. You cannot use it with the Pretérito Perfeito. Falei-te is fine (Enclisis), but falar-te-ei is only for the future. Many learners also forget the second hyphen. You need both to keep the sandwich together! Finally, watch out for the magnetic words. Placing a pronoun in the middle of a verb when não is present is a major red flag. It shows you haven't mastered the hierarchy of pronoun placement. Remember: magnets always win over the sandwich.

Let's compare the three types of pronoun placement. Próclise is the pronoun before the verb: Eu te amo. This is the most common, especially in Brazil. Ênclise is the pronoun after the verb: Amo-te. This is the standard in Portugal for starting sentences. Mesóclise is the middle child: Amar-te-ei. It only exists for the future. Think of Próclise as your jeans and t-shirt. Ênclise is a nice button-down shirt. Mesóclise is a full three-piece suit. You wouldn't wear a suit to the gym, and you wouldn't wear a t-shirt to meet the President. Choosing the right one depends entirely on the "dress code" of your situation. In modern Brazilian Portuguese, people often use the ir + infinitive construction to avoid this entirely. Instead of Dar-te-ei, they say Vou te dar. It is much easier and very common.
