ter and the agreeing participle with ser or estar to master this structure.
Grammar Rule in 30 Seconds
Use 'ter' for active actions you perform, and 'ser' for passive states or actions done to you.
- Use 'ter' + past participle for active voice: 'Eu tenho comido' (I have been eating).
- Use 'ser' + past participle for passive voice: 'O bolo foi comido' (The cake was eaten).
- Past participles with 'ser' must agree in gender and number with the subject.
Overview
The Portuguese Particípio Passado (Past Participle) is a fundamental verb form crucial for constructing compound tenses, forming the passive voice, and functioning as an adjective. Mastery of the past participle is essential for learners at the B2 CEFR level, enabling you to express complex temporal relationships and describe states resulting from actions. This reference clarifies its intricate behavior, particularly the critical distinction when used with auxiliary verbs ter (to have) versus ser (to be) or estar (to be).
Linguistically, participles bridge the gap between verbs and adjectives, conveying completed action while often modifying a noun or pronoun. Their flexibility is a hallmark of many Indo-European languages, and Portuguese maintains this dual nature. Understanding this core function is key to grasping why the participle sometimes changes form and sometimes remains invariable.
How This Grammar Works
Ter Rule: Invariabilityter (or haver, predominantly in European Portuguese), it forms compound tenses, indicating actions completed by the subject. In these constructions, the participle remains absolutely invariable, always retaining its masculine singular -o ending, regardless of the gender or number of the subject or direct object. This invariability reflects its verbal nature within the compound tense, where ter carries the inflection for person, number, and tense.Eu tenho escrito muitas cartas. (I have written many letters.) Here, escrito is invariable, despite cartas being feminine plural. The action of writing (escrever) has been completed by the subject Eu via the auxiliary tenho. Similarly, Nós tínhamos comprado os bilhetes. (We had bought the tickets.) Comprado stays masculine singular, detached from the plural bilhetes.Ser/Estar Rule: Agreementser or estar, it functions either to form the passive voice (ser) or to describe a resultant state or condition (estar). In these cases, the participle behaves like an adjective, agreeing in gender and number with the noun or pronoun it modifies. This agreement signifies its adjectival role, describing a quality or state of the subject.A porta foi fechada. (The door was closed.) Fechada agrees with A porta (feminine singular). If the subject changes, so does the participle: As portas foram fechadas. (The doors were closed.) And with estar: Os livros estão lidos. (The books are read.) Here, lidos matches Os livros (masculine plural). The agreement is crucial for conveying accuracy in these descriptive or passive constructions.Ter | Compound Tenses (active voice) | Invariable (always -o) | Eu tenho falado.Ser | Passive Voice | Agrees (gender/number) | A carta foi falada.Estar | Resultant State/Adjective | Agrees (gender/number) | Ela está calada.Formation Pattern
verbos abundantes). Mastering these variations is critical for B2 learners.
-ar, -er, -ir) and adding a specific suffix:
-ar verbs, replace -ar with -ado.
falar (to speak) → falado
comprar (to buy) → comprado
trabalhar (to work) → trabalhado
-er and -ir verbs, replace the ending with -ido.
comer (to eat) → comido
viver (to live) → vivido
partir (to leave) → partido
-ado/-ido pattern. These forms are often strong, or root-changing, and derive directly from Latin perfect passive participles. They must be memorized, as there is no predictable rule for their formation. Examples:
abrir | aberto | opened |
cobrir | coberto | covered |
dizer | dito | said, told |
escrever | escrito | written |
fazer | feito | done, made |
pôr | posto | put, placed |
romper | roto | broken, torn |
ver | visto | seen |
vir | vindo | come, arrived |
ter and ser/estar constructions. For instance, Eu tinha visto o filme. (I had seen the film.) and O filme foi visto por todos. (The film was seen by everyone.) The form visto is used in both cases.
Verbos Abundantes):
verbos abundantes (abundant verbs), possess both a regular (-ado/-ido) and an irregular past participle form. The choice between these two forms is strictly dictated by the auxiliary verb.
-ado/-ido) is used exclusively with ter (or haver) to form compound tenses.
ser or estar (or ficar) for the passive voice or to denote a resultant state/adjective.
verbos abundantes:
ter) | Irregular Form (with ser/estar) | Meaning |
aceitar | aceitado | aceito | accepted |
acender | acendido | aceso | lit, turned on |
anexar | anexado | anexo | attached |
entregar | entregado | entregue | delivered, handed |
exprimir | exprimido | expresso | expressed |
ganhar | ganhado | ganho | earned, won |
gastar | gastado | gasto | spent, worn out |
matar | matado | morto | killed, dead |
pagar | pagado | pago | paid |
suspender | suspendido | suspenso | suspended |
Eu tinha entregado o pacote. (I had delivered the package.) vs. O pacote foi entregue. (The package was delivered.) Notice entregado is invariable with tinha, while entregue would agree if the subject were plural or feminine (e.g., As encomendas foram entregues.).
Pagar: While the rule for verbos abundantes is generally consistent, the verb pagar presents a common regional variation. In Brazilian Portuguese, ter pago is widely accepted and used for the compound tense, even though pagado is the theoretically regular form. In European Portuguese, ter pagado is more strictly preferred for the compound tense, reserving pago for use with ser/estar. However, estar pago/ser pago is universal. It is safer to follow the ter + regular, ser/estar + irregular rule unless you are explicitly aiming for a colloquial BP style.

Cultural Notes
Brazilians often use 'ter' where European Portuguese might use 'haver', but the 'ter' vs 'ser' rule remains the same.
In Portugal, the passive voice is slightly more common in formal writing than in Brazil.
Similar to Brazil, 'ter' is the preferred auxiliary for compound tenses.
Both 'ter' and 'ser' derive from Latin 'tenere' and 'esse'.
