Altruism

1. Definition + Rich Everyday Explanation

Altruism (noun) = selfless concern for the wellbeing of others, even at a cost to yourself.

Altruism is helping others without expecting anything in return. It’s not about looking good, feeling good, or gaining advantage — it’s about genuinely caring for other people’s welfare and acting on that care even when it costs you time, money, comfort, or safety. True altruism asks: “What do they need?” not “What do I get?”

In everyday modern English, “altruism” appears in discussions about morality, charity, volunteering, and human nature. Philosophers debate whether pure altruism exists or whether all helping behaviour secretly serves the helper. Biologists study altruism in animals — why would a creature risk its life for another? Charities appeal to people’s altruism when asking for donations.

The word carries a tone of admiration and idealism. Describing someone as altruistic is high praise — it suggests they’re genuinely good, not just performing goodness for an audience. However, the word can also appear in sceptical contexts: “Is it really altruism, or does she just want recognition?”

Altruism signals moral excellence and selflessness. It represents what many consider the highest form of human behaviour — putting others first without calculation or self-interest.

Examples from the street:

• “She donated her kidney to a stranger — that’s pure altruism” → she helped someone with no personal benefit
• “His altruism is inspiring — he spends every weekend volunteering” → his selfless behaviour motivates others
• “Is true altruism even possible, or are we always serving ourselves somehow?” → a philosophical question about human motivation

2. Most Common Patterns

• pure/true altruism → selfless behaviour with absolutely no hidden self-interest
• act of altruism → a specific selfless deed
• altruism toward/towards + group → selfless concern directed at specific people
• out of altruism → motivated by selfless concern rather than personal gain
• altruistic + noun → (adjective form) describing selfless behaviour or people
• show/display altruism → demonstrate selfless concern through actions
