Non-finite verb forms: no comer, fue caminando...

Formas no personales del verbo: no comer, fue caminando...


Las formas no personales del verbo se usan para hablar de acciones sin decir quién las hace ni cuándo pasan.

(Non-finite verb forms are used to talk about actions without saying who does them or when they happen.)

Infinitive, gerund, participle: the quick decision

  • Infinitive = the action in general (“to…”) or as a noun.
  • Gerund (gerundio) = an action in progress or the way/method something happens (“…ing”).
  • Past participle (participio) = the result/state after an action (“done/finished”).
Question to ask Use Typical Spanish shape
“What is the rule / activity in general?” Infinitive fumar, visitar, mudarse
“Is it happening right now / while…?” Gerund fumando, visitando, buscando
“What is the state now (as a result)?” Participle amueblado, cerrado, hecho

Infinitive: rules, plans, and “verb + verb”

  • Signs, rules, instructions often use infinitive (impersonal, neutral):
    • No fumar en el edificio.
    • No aparcar en la entrada.
  • After many common verbs, Spanish uses infinitive (not “-ing”):
    • Queremos visitar el piso.
    • Necesito hablar con la propietaria.
    • Vamos a firmar el contrato.
  • As a “thing” (an activity as a concept):
    • Mudarse es estresante.
    • No sé si mudarse ahora es buena idea.

Self-check: If you can replace it with “the act of …” in English, you probably need infinitive.

Gerund (gerundio): in progress vs. “how/what way”

  • Action in progress (very often with estar):
    • Está haciendo la mudanza. (in progress)
    • Estamos buscando piso.
  • Short answers to “What are you doing?”:
    • —¿Qué haces? —Buscando piso.
  • How / in what way something happens (method, manner):
    • Fue caminando hasta la empresa de mudanzas. (= she went on foot / by walking)
    • Aprende comparando precios. (= by comparing)

Key idea: The gerund is not “any -ing”. It is mainly for progress or method/manner.

Participle: “estar + participle” describes a state (result)

  • Use estar + participle for the current condition of something.
  • Very common in housing, admin, and professional contexts.
Meaning Correct Wrong
State/result now El piso está amueblado. El piso está amueblando.
Door/window state La puerta está cerrada. La puerta está cerrando.

Self-check: If you mean “already done / already in that condition”, choose participle.

Common traps for English speakers (and how to avoid them)

  • Trap 1: Using gerund after a verb just because English uses “-ing”.
    • Correct: Quiero visitar el piso.
    • Wrong: Quiero visitando el piso.
  • Trap 2: Confusing “progress” with “state”.
    • Progress: Están amueblando el piso. (they are furnishing it right now)
    • State/result: El piso está amueblado. (it is furnished already)
  • Trap 3: Overusing the gerund to mean “after” or “and then”.
    • Better: Salió y fue a la inmobiliaria.
    • Use gerund only if it answers how/while: Fue caminando.

1.
Incorrect: with «estar» to describe a state, the past participle («amueblado») is used, not the gerund («amueblando»).
2.
Incorrect: the natural word order in Spanish for this case is «fuimos caminando» or «fuimos andando»; here the sentence is inverted in an unnatural way if one intends to use «al final» at the beginning — better to keep «Al final fuimos caminando...».
