Ficar vs Tornar-se

English says become and leaves it at that. Portuguese makes you choose — and once you look closely, "become" turns out to hide about ten different verbs in PT-PT, each sensitive to whether the change is a mood, an identity, a profession, a metamorphosis, a gradual slide, or an institutional shift. This page maps the full landscape so you know which verb to reach for in each situation.

The central split is this: ficar is the estar-flavoured "become" (state, mood, condition, physical change), while tornar-se is the ser-flavoured "become" (identity, role, essence). Everything else — transformar-se em, passar a ser, passar a + infinitive, virar, converter-se, fazer-se de, ir + gerund — specialises one of those two core moves. In everyday PT-PT speech, ficar does the bulk of the work; tornar-se belongs more to writing and formal register; and a learner who grabs tornar-se for a passing emotion ends up sounding like a badly translated press release.

The core split in one sentence

Ficar = the subject ends up in a new state or condition — often temporary, often emotional, often a change you can point to in a moment. Tornar-se = the subject turns into something more lasting — a new identity, role, or fundamental quality.

1. Ficar — the everyday workhorse

Ficar already means "to stay," "to remain," and "to be located." Its "become" sense is a natural extension: the subject ends up somewhere — physically, emotionally, or situationally. This gives ficar an enormous productive range in PT-PT.

Emotional reactions

Physical states and conditions

Becoming + adjective (the big productive use)

Almost any gradable adjective pairs with ficar to mean "become [that way]." In PT-PT, even outcomes we might think of as lasting — ficar famoso, ficar rico, ficar viúva — sound perfectly natural with ficar in speech.

Weather and time-of-day

Ficar sem — running out of

Fixed ficar collocations

2. Tornar-se — the identity shift

Tornar-se is reflexive, followed either by a noun (tornou-se presidente) or an adjective (tornou-se famoso). It carries the weight of a more definitive change — the subject does not merely end up a certain way, they turn into something. It is common in writing, biography, essays, obituaries, and formal speech, and it is the default choice when you want to signal that the change is lasting or defining.

Professions and roles

Lasting qualities and identities

Political, social, and historical shifts

3. Tornar (não-reflexo) — "to make [someone / something X]"

Without the reflexive pronoun, tornar is transitive: an external cause makes the object a certain way. It always takes a direct object plus an adjective or noun predicate.

Compare the reflexive and the transitive uses carefully: tornou-se arrogante (she became arrogant — her own transformation) vs tornou-a arrogante (something made her arrogant — external cause). The first describes the subject's evolution; the second names a cause that changed someone else.

4. Passar a ser — the formal institutional shift

Passar a ser means "to come to be" — the official, gradual, or institutional acquisition of a new identity. It is formal and common in academic, journalistic, and legal writing. The emphasis is on a deliberate or decreed change, often with a date attached.

Passar a ser is not used for emotional states or sudden changes. If someone got upset, you do not say passou a ser chateado — you say ficou chateado.

5. Passar a + infinitive — "to start doing"

A separate and very common construction: passar a + infinitive means to start doing [something] as a new habit, rule, or routine. It describes the beginning of a new pattern, usually with an implied contrast to what came before. This is not quite "become" in the English sense, but it is where English speakers often reach for "became" + gerund ("he became working from home" → wrong) — PT-PT handles this structure with passar a.

Notice the sharp contrast with começar a + infinitive (to start doing — one-off, not necessarily habit-forming). Passei a correr todos os dias implies a new routine that has settled in; comecei a correr todos os dias can refer to the starting point of an activity without the same sense of entrenched pattern.

6. Transformar-se em — literal or dramatic metamorphosis

Transformar-se em is the strongest "become": a real metamorphosis, literal (fairy tales, physics, biology) or dramatic-metaphorical. It requires em + noun and cannot take a bare adjective.

You would not say transformou-se triste — for an adjectival change you fall back to ficou triste or tornou-se triste.

7. Virar — restricted in PT-PT

Virar literally means "to turn," and by extension "to turn into / become." In Brazilian Portuguese this sense is extremely productive (virei vegetariano, virou médico). In PT-PT, the "become" use of virar is narrower — mostly weather, times of day, and a handful of set expressions. Virar + profession (virou médico) is a mild brasileirismo; PT-PT speakers use tornou-se médico or ficou médico instead.

8. Converter-se — ideological and religious conversion

Converter-se (a / em) is the verb for a conscious change of faith, ideology, or belief — and, in a more technical sense, for physical or chemical transformation. It is formal to neutral in register and has two preposition patterns:

• converter-se a
  • noun (faith / ideology) — converteu-se ao islão
• converter-se em
  • noun (physical / chemical transformation) — converter-se em pedra

For everyday "became a vegan / became a Christian," PT-PT accepts both converteu-se ao veganismo (more formal) and ficou vegan / tornou-se cristão (more neutral).

9. Fazer-se de / fazer-se passar por — pretending to be

Fazer-se de + adjective or noun means "to act / pretend to be [X]" — a performed state, not a real change. Fazer-se passar por is stronger: "to pass oneself off as." Both are colloquial to neutral in register and are indispensable for any social conversation in Portugal.

Common fazer-se de collocations: fazer-se de parvo / estúpido / burro (play dumb), fazer-se de forte (act tough), fazer-se de difícil (play hard to get), fazer-se de desentendido (play innocent), fazer-se de vítima (play the victim).

10. Ir + gerund / ir ficando / ir + adverbial — the PT-PT gradual-change construction

This is one of the most characteristically European Portuguese ways of expressing a gradual, ongoing change: ir + gerund or ir + ficando / sendo + adjective. It signals that the change is happening progressively, bit by bit, over time. Where English says is gradually becoming, is growing, is getting to be, PT-PT reaches for ir + gerund constructions.

Note the clitic placement in vou-me habituando — the reflexive attaches to the finite ir, not to the gerund. This is the standard PT-PT pattern.

11. Chegar a ser — rare in PT-PT

Spanish speakers often reach for llegar a ser to mean "to become / end up being." In PT-PT this exact construction (chegar a ser) is rare — you hear it occasionally but it sounds slightly translated. The natural PT-PT equivalents are tornar-se, vir a ser, or acabar por ser.

If you are importing llegar a ser from Spanish, retire it and use tornar-se or acabar por ser instead.

The register ladder — same idea, three levels

The same thought can be expressed across a register spectrum. A learner who knows only one rung on the ladder sounds one-note; a learner who controls all three chooses the register to match the situation.

All three are correct; the register shifts. A friend telling you about a famous director would say ficou; a newspaper profile would say tornou-se; a doctoral thesis would say passou a ser.

Decision grid

Note on seasons: chegou o inverno is the most idiomatic PT-PT option; fez-se inverno is more literary; virou inverno is colloquial. You should not say ficou inverno — that construction does not work in PT-PT.

Spanish-speaker contrast — the map you actually need

Spanish speakers are the largest group of learners of Portuguese, and the "become" territory is where Spanish intuitions cause the most trouble. Here is the direct mapping.

The single most useful insight for a Spanish speaker: Spanish quedarse maps almost one-to-one onto Portuguese ficar — both verbs mean "to stay / remain" and both extend to "end up in a state." If you have good intuition for when Spanish uses quedarse, use ficar in the same places.

Translation drill — English "become" mapped to PT-PT verbs

English flattens all of these into a single verb. Here is how native PT-PT speakers handle each case.

Note how "became aware" does not take any "become" verb in PT-PT — Portuguese uses dedicated verbs (aperceber-se de, dar-se conta de, reparar em) for cognitive transitions. English speakers often over-reach for a "become" verb here; resist the urge.

The PT-PT productivity of ficar — why it is so dominant

One reason ficar dominates in PT-PT is that the verb is also the everyday word for "to stay" and "to be located." That gives it a flexible, all-purpose feel — it describes where things land, physically, emotionally, or situationally.

The "becoming" sense is a natural extension of "ending up [in a state]," and PT-PT speakers feel this connection in their bones. When in doubt in speech, ficar is almost always safe.

Common mistakes

Key takeaways

• Ficar is the default "become" in spoken PT-PT. It covers moods, physical states, running-out-of, weather, and most adjectival changes.
• Tornar-se is more written and more formal, used for professions, lasting identities, and definitive transformations. It is reflexive and takes a noun or an adjective.
• Tornar (without the reflexive) is transitive: tornar alguém arrogante — "to make someone arrogant."
• Passar a ser is formal written, ideal for institutional or abstract shifts with a date.
• Passar a + infinitive marks the beginning of a new routine or habit.
• Transformar-se em signals a literal or dramatic metamorphosis; requires em
  • noun.
• Converter-se a / em handles religious, ideological, and physical/chemical conversion.
• Fazer-se de / fazer-se passar por is about pretending, not becoming.
• Ir + gerund and ir ficando / sendo express gradual, ongoing change — a PT-PT signature move.
• Virar for "become" is brasileiro in most uses; in PT-PT, keep it to weather, times of day, and set expressions.
• Spanish speakers: map quedarse → ficar, hacerse → tornar-se / ficar, convertirse en → transformar-se em / tornar-se, and avoid calqueing llegar a ser.
• When unsure in speech, ficar is almost always safe.
