“Slaughter in” or “slaughter by” ?

Slaughter is usually used without a fixed preposition. By commonly introduces the agent or method, while in often adds location or context.

Quick answer

How to use slaughter with prepositions

Use slaughter by to name who carried out the killing or what caused it. Use slaughter in when in introduces a place, conflict, or event rather than completing the verb itself.

Thousands were slaughtered by invading forces.
Civilians were slaughtered in the attack.
The herd was slaughtered by disease and starvation.

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using in as if it were required by the verb

In usually adds place or context, not a required complement.

✕ They slaughtered in the villagers. ✓ They slaughtered the villagers.

Confusing by and with

By names the agent; with names the tool or method.

✕ The civilians were slaughtered with rebels. ✓ The civilians were slaughtered by rebels.
