What Happened To It: Passive Sentences

A sentence in this news article said: Los pájaros, casi todos pollitos pero también pavos y otras aves, fueron ayudados después de ser vistos en Delaware.

“Los pájaros fueron ayudados.”

I had never seen the verb ayudar expressed as “ayudados“

I found that:

“Los pájaros fueron ayudados.” is a passive sentence
- When the subject (birds) has something done to it/them, the sentence becomes passive
The verb (ayudados) sounds like it’s in the past tense when translated to english but:
- It’s actually a past participle
  - ayudar ->ayudado (-ido/-ado)
- which is used like an adjective
  - matches number and gender (ayudados)
- but it’s not called an adjective, just a past participle

In Spanish, the past participle (in the passive voice)
isn’t technically an adjective, but it looks like one and acts like one
— it agrees in gender and number, follows the noun, and describes its state
— so I don’t care what it’s called, it behaves like an adjective, and that’s how I’m treating it.

✅ What does “with modals” mean?

It just means using words like “can, should, might, must, could” before the passive voice structure.

These words are called modals, but you don’t need to remember that. Just think of them as helpers that express:

Possibility (can, might)
Obligation (should, must)
Permission (may)
Ability (could)

🔹 English structure:

Modal + be + past participle

Examples:

The cake can be eaten cold.
The door should be locked at night.
The rules must be followed.
The dog might be adopted tomorrow.

🔸 Spanish structure:

[Modal] + ser + participio pasado

Spanish uses verbs like:

poder → can / might
deber → should / must
tener que → have to
haber que → (it has to be done — general)

Examples:

El pastel puede ser comido frío.
La puerta debe ser cerrada por la noche.
Los errores tienen que ser corregidos.
Este formulario debe ser firmado antes del viernes.

🧠 Just think:

If you’re saying “should be done” or “can be fixed” — you’re in modal + passive land.
