### sense in the lessons

In stories and history lessons (Greek myths, the Iliad, the Trojan War) the word tells the reader about Troy and its war with the Greeks. In computing and online safety lessons, a «trojan» or «Trojan horse» warns pupils not to download unknown files: something that looks like a gift may hide danger. Phrases: «the Trojan War», «the Trojan Horse», «a Trojan horse» (any trick that gets an enemy inside), «work like a Trojan».

### note

Write «Trojan» with a capital letter when it means Troy or its people; the computer word is often written in small letters, «a trojan». Countable: a Trojan, Trojans. The Trojan Horse is a story from Greek myth and poems; historians are not sure it really happened. «Beware of Greeks bearing gifts» comes from this story. A trojan is not exactly a virus: a virus copies itself, a trojan tricks you into letting it in.
