The act of killing a friend; murder or killing of someone you're friendly with.
From Latin 'amicus' (friend) plus '-cide' (killing), constructed similarly to 'suicide' or 'homicide' to describe the specific type of killing.
Amicicide is a brutal word that barely exists in English because we usually just say 'killing a friend'—but it technically exists, making it one of those words that's grammatically correct but too dark to use in regular conversation.
