Portuguese Mesoclisis: Splitting Verbs for Ultimate Formality (-lo-ei, -lhe-á)
Grammar Rule in 30 Seconds
Mesoclisis is the formal insertion of an object pronoun inside a verb, specifically used with the future tense.
- Only use it with the Future of the Present (Futuro do Presente) or Future Preterite (Futuro do Pretérito).
- The pronoun must be placed between the verb root and the ending: 'dar-lhe-ei'.
- Never use mesoclisis if a word requiring proclisis (like 'não') precedes the verb.
Overview
Portuguese mesoclisis, or mesóclise, represents one of the most sophisticated and formal constructions within the language. It involves inserting certain unstressed object pronouns directly into the middle of a verb form, specifically between the verb stem and its tense ending. This grammatical phenomenon is largely confined to the Future Indicative (futuro do presente) and the Conditional (futuro do pretérito) tenses.
Historically, mesoclisis is a relic of Latin grammatical structures, preserved with greater fidelity in Portuguese than in many other Romance languages. Its persistence reflects a deeper linguistic principle: the avoidance of starting a sentence with an unstressed object pronoun, especially prevalent in European Portuguese. This rule, known as proclisis avoidance, means that if a pronoun cannot precede the verb (due to sentence-initial position or lack of a 'proclitic magnet'), and it cannot follow the verb in its standard enclitic form (due to specific tense rules), it must then split the verb.
This mechanism is crucial for understanding the 'why' behind this seemingly complex structure.
While largely absent from casual spoken Brazilian Portuguese, mesoclisis remains a hallmark of formal written communication, legal texts, academic discourse, and elevated speech in both Portuguese (PT-PT) and Brazilian Portuguese (PT-BR). Mastery of mesoclisis signifies a high level of linguistic proficiency, placing you firmly in the C1 Advanced CEFR level. It showcases not only grammatical precision but also an appreciation for the historical elegance of the language.
Consider the simple phrase "I will help you." In a casual setting, you might say Eu te ajudarei. In a formal context where mesoclisis is required, it transforms into Ajudar-te-ei. The change is not just stylistic; it reflects a distinct grammatical pathway for pronoun placement in specific tenses, conveying a heightened degree of respect and formality.
How This Grammar Works
haver (to have). For example, falar-ei (I will speak) originally derived from falar + hei (I have to speak).fazer (to do) in the Future Indicative first-person singular: farei. If you need to insert the object pronoun o (him/it), standard enclisis (farei-o) is not permitted in this tense. Similarly, proclisis (o farei) might be disallowed if the sentence begins directly with the verb or lacks a proclitic trigger.o is inserted: fá-lo-ei. This seemingly unusual structure is, in fact, the most logical and historically consistent placement when considering the verb's etymology.- Negative adverbs:
não,nunca,jamais,ninguém - Adverbs (general):
já,sempre,muito,pouco,bem,mal,aqui,ali,hoje,ontem - Relative pronouns:
que,quem,onde,cujo - Indefinite pronouns:
alguém,tudo,nada,outrem - Interrogative pronouns/adverbs:
quem?,onde?,como? - Conjunctions:
embora,que(as a conjunction)
Não fá-lo-ei. The correct form is Não o farei because não acts as a powerful proclitic magnet. Similarly, Quem te diria isso? (Who would tell you that?) uses proclisis due to quem, even though diria is in the Conditional.Formation Pattern

-r, -s, or -z, and is followed by o, a, os, or as, the final consonant of the infinitive is dropped, and the pronoun takes an initial l- (lo, la, los, las). Additionally, if the preceding vowel of the verb stem is a or e, an acute accent (´) is added.
-r: The -r is dropped. The pronoun becomes lo/la/los/las. If the vowel before the -r is a or e, an accent is added.
comprar | o | -ei | Comprá-lo-ei | I will buy it |
vender | a | -á | Vendê-la-á | He/She will sell it |
fazer | os | -emos | Fá-lo-emos | We will do them |
-s or -z: This occurs mainly with irregular verbs or when the infinitive is used with a direct object pronoun that also acts as a reflexive or reciprocal (e.g., por-se-á, fazê-los-ei). The process is identical: drop the consonant, add l, and accent if needed. Fazer's irregular stem for the future/conditional is far- (or fá- before l).
dizer, fazer, and trazer. You must use their irregular stems before applying the pronoun insertion rule.
Dizer (to say/tell): Irregular stem is dir-.
dizer | lhe | -ei | Dir-lhe-ei | I will tell him/her |
dizer | o | -ão | Di-lo-ão | They will say it |
Fazer (to do/make): Irregular stem is far-.
fazer | me | -ia | Far-me-ia | He/She would do me |
fazer | a | -ás | Fá-la-ás | You will do it |
Trazer (to bring): Irregular stem is trar-.
trazer | nos | -emos | Trar-nos-emos | We will bring us |
trazer | os | -iam | Trá-los-iam | They would bring them |
dizer, fazer, trazer, when o/a/os/as are inserted, the r of the irregular stem (dir-, far-, trar-) is also dropped, and the l is added (di-lo-á, fá-lo-ei, trá-la-ás). The accentuation rules remain the same.
When To Use It
- Legal Documents: Contracts, court rulings, official declarations. Here, mesoclisis is often mandatory, particularly in PT-PT, to ensure legal precision and traditional formality. For example,
Conceder-se-á o benefício(The benefit will be granted). - Academic Writing: Theses, dissertations, scholarly articles, especially in fields like law, history, or literature, may employ mesoclisis to lend gravitas and academic rigor. You might encounter
Analisar-se-ão os dados(The data will be analyzed). - Official Correspondence: Formal letters, governmental decrees, or diplomatic communications. A phrase like
Informar-vos-ei prontamente(I will inform you promptly) elevates the tone.
- Public Speeches: Presidential addresses, ceremonial orations, or solemn declarations, particularly in PT-PT, frequently feature mesoclisis. A politician might declare,
Defender-me-ei de todas as acusações(I will defend myself from all accusations). - Journalism (PT-PT): In European Portuguese, mesoclisis is still regularly found in high-quality newspaper articles, especially in headlines or reports on official matters, reflecting a generally more conservative approach to grammar.
Fará-se o anúncio amanhã(The announcement will be made tomorrow).
- Classic Literature: Reading authors like Machado de Assis (PT-BR) or Eça de Queirós (PT-PT) will expose you extensively to mesoclisis. It was standard usage in their eras. Understanding it is essential for literary comprehension:
Amar-te-ei eternamente(I will love you eternally). - Historical/Political Dramas (Netflix/Film): Subtitles or dialogue in period pieces often retain mesoclisis to evoke the language of the time. This is a practical application for C1 learners focusing on comprehension.
- European Portuguese (PT-PT): Mesoclisis is a much more integrated and expected part of the formal register. It is not considered archaic but rather proper and elegant in appropriate contexts. The rule against starting a sentence with an unstressed object pronoun is very strong, making mesoclisis a frequent necessity (
Dar-lhe-ei o livro). - Brazilian Portuguese (PT-BR): While recognized as grammatically correct, mesoclisis is almost universally considered archaic or excessively formal in spoken language. In writing, it is reserved for the highest echelons of formality (legal, academic, highly official). Using it in casual conversation would sound highly affected, even sarcastic. The more common alternatives involve proclisis (
Eu te darei o livro) or auxiliary verbs (Vou te dar o livro). However, for comprehension of formal texts or classical literature, PT-BR speakers and learners still need to understand it.
- Casual conversations or informal emails.
- Text messages or social media posts (unless for ironic effect).
- Any context where a proclitic magnet (like
não,que,sempre) is present – this is a fundamental error.

Fá-lo-ei.(I will do it.)
- Incorrect:
Dizer-lhe-ia.(Using infinitivedizerstem instead ofdir-) - Correct:

Vossa Excelência, informar-te-ei da decisão. - Correct:
Vossa Excelência, informar-vos-ei da decisão.(More formal 'vos' for plural address) - More Common/Formal:
Vossa Excelência, informá-lo-ei da decisão.(TreatingVossa Excelênciaas third person, usingofor masculine,afor feminine, orlhefor dative)
Vossa Excelência typically demand third-person agreement for verbs and pronouns (o, a, lhe, se). Using te with such a formal address is contradictory.Real Conversations
