Introduction
Learning Portuguese verbs that change meaning with small additions is a common challenge. One of the clearest examples is the verb esquecer, which can appear alone or with the preposition de. This article explains how to use esquecer in Brazilian Portuguese, shows conjugations and example sentences, and highlights differences in meaning, syntax, and common mistakes.
Overview: esquecer vs esquecer de
The verb esquecer means to forget. In Brazilian Portuguese, it appears in two main patterns: esquecer + noun (or direct object) and esquecer de + verb or noun. Each pattern has specific uses and subtle differences in nuance. Understanding when to omit or include de will improve both comprehension and fluency.
Basic forms and conjugation
Esquecer is a regular -er verb with an irregular past participle (esquecido or esquecido depending on context, but commonly esquecido). Here are the present tense forms for quick reference:
eu esqueço
tu esqueces
ele/ela/você esquece
nós esquecemos
vós esqueceis
eles/elas/vocês esquecem
Note that in spoken Brazilian Portuguese, vós is rarely used and você/vocês are common for informal and formal second-person forms.
Using esquecer without de
When esquecer appears without de, it often takes a direct object and is used to say that someone forgets a thing, a person, or an action (expressed as a nominalized idea). This structure is similar to English forget something.
Structure and examples
Structure: subject + esquecer + direct object (noun or pronoun)
Examples:
Eu esqueci a chave em cima da mesa.
Ele esqueceu o nome dela.
In these sentences, the object (a chave, o nome dela) is directly connected to the verb. The verb focuses on the item or fact that was forgotten.
Pronouns as direct objects
When using personal pronouns, Brazilian Portuguese prefers clitic pronouns placed after the verb in affirmative sentences, often attached to the verb as enclitics (me, te, o, a, nos, os, as). In casual speech, you will also hear stressed forms for emphasis.
Examples:
Eu esqueci te avisar. (colloquial)
Eu te esqueci. (less common for forget someone; usually means I forgot you)
For forgetting people, Portuguese speakers commonly say Eu esqueci dela para express forgetting about someone in certain contexts, but grammar prefers Eu me esqueci dela or Eu me esqueci de que ela existia for reflexive nuance.
Using esquecer de + infinitive
When esquecer is followed by de, it commonly precedes an infinitive verb or a noun introduced by the preposition. This construction is used to express forgetting to do something or forgetting about something in a more explicit way. Grammatically, esquecer de functions like forget to + verb or forget about + noun in English.
Structure and examples with infinitives
Structure: subject + esquecer + de + infinitive
Examples:
Eu esqueci de ligar para minha mãe ontem.
Nós esquecemos de comprar pão.
These sentences emphasize the action that was forgotten. Use esquecer de when you want to highlight that the person failed to perform a specific action.
Structure and examples with nouns
Structure: subject + esquecer + de + noun
Examples:
Ele esqueceu de seu guarda-chuva no ônibus.
Você esqueceu de compromisso importante.
Although a direct object without de is possible, speakers often use esquecer de with nouns when the emphasis is on the act of forgetting itself or to clarify the relationship between verb and object.
Meaning differences and nuance
Sometimes both patterns are grammatically acceptable but carry different nuances. The version without de often treats the object as a completed fact: the thing was forgotten. The version with de can stress the failure to do something or the mental action of forgetting.
Contrast examples
Eu esqueci a carta. (I forgot the letter is somewhere; the letter was left behind, as a fact.)
Eu esqueci de enviar a carta. (I forgot to send the letter; emphasizes the missed action.)
Eu esqueci a roupa na lavanderia. vs. Eu esqueci de pegar a roupa na lavanderia.
The first sentence tells where the clothes were left. The second tells that the speaker failed to pick them up.
Reflexive and pronominal uses
Esquecer can be used reflexively: esquecer-se de. This is common in both European and Brazilian Portuguese, and it emphasizes the subject’s experience of forgetting. In spoken Brazilian Portuguese, the reflexive pronoun is often placed after or before the verb depending on emphasis and formality.
Examples of esquecer-se de
Eu me esqueci de avisar você.
Ela se esqueceu de pagar a conta.
Compare with non-reflexive forms: Eu esqueci a conta. vs Eu me esqueci de pagar a conta. The reflexive highlights the subject’s internal lapse.
Negative and interrogative forms
Negatives and questions follow standard Portuguese word order. When negating, place não before the verb or the reflexive pronoun depending on emphasis.
Negative examples
Eu não esqueci a reunião.
Ela não se esqueceu de confirmar o horário.
Questions and emphasis
Você esqueceu de trazer os documentos?
O que você esqueceu?
In questions, choose the pattern that matches what you want to ask: forgot the object itself or forgot to do something.
Common mistakes and tips
Many learners confuse the two patterns because English uses forget both with direct objects and with infinitives without a preposition (I forgot the letter / I forgot to call). Remember these tips:
-
Use esquecer + noun when referring to the object itself or when the object is a noun phrase: Eu esqueci a chave.
-
Use esquecer de + infinitive to say you forgot to do something: Eu esqueci de trancar a porta.
-
Prefer reflexive esquecer-se de for polite or more natural phrasing in many contexts: Eu me esqueci de trazer o documento.
-
When in doubt about an action, use esquecer de + infinitive to be safe: Eu esqueci de confirmar / Eu esqueci de comprar.
Pronoun placement quick guide
In spoken Brazilian Portuguese, clitic pronouns often attach to the verb after it in affirmative sentences: me, te, se, o, a, nos, os, as. In negative and compound tenses, pronouns usually come before the verb.
Examples:
Me esqueci de ligar. (colloquial)
Eu não me esqueci de nada.
Regional and informal variations
Brazilian Portuguese is diverse. In some regions and registers, speakers may prefer one structure over the other. Informally, people often omit the reflexive particle or use contraction and elision. In rapid speech, esquecer + object and esquecer de + infinitive can sound very similar, so context is key.
Common colloquial examples
Caramba, esqueci meu celular em casa.
A gente esqueceu de combinar o horário.
Note the use of a gente instead of nós in casual speech, which is widespread in Brazil and affects verb conjugation (a gente + 3rd person singular).
Cultural and usage notes
Forgetting in Brazilian culture often prompts polite apologies and explanations. Saying Desculpa, eu me esqueci de… or Foi mal, eu esqueci de… is a common, friendly way to take responsibility. Using the reflexive form can sound more personal and apologetic, which fits many social situations.
Politeness and clarifying responsibility
Eu me esqueci de te avisar carries a different interpersonal tone than Eu esqueci o aviso. The reflexive form acknowledges personal responsibility more explicitly, which is useful in apologies or professional settings.
Summary of rules
Use this short checklist to choose the right form:
-
If you forgot an object: prefer esquecer + noun or pronoun. Example: Eu esqueci a bolsa.
-
If you forgot to perform an action: use esquecer de + infinitive. Example: Eu esqueci de ligar.
-
To emphasize the internal lapse or responsibility: use reflexive esquecer-se de. Example: Eu me esqueci de pagar a conta.
-
In negative and compound tenses, place pronouns before the verb. Example: Eu não me esqueci.
Conclusion
Mastering esquecer and the use of de will make your Portuguese sound more natural and precise. Remember: esquecer + noun for forgotten items, esquecer de + infinitive for forgotten actions, and esquecer-se de to convey personal lapse. With practice and exposure to real Brazilian Portuguese sentences, choosing the correct form becomes intuitive.
