Morphology

Trojan + horse

The malware sense of 'trojan horse' depends on the mythological story of a deceptive wooden horse and is a conventionalized metaphor; a learner who only knows the literal constituents ('Trojan' as from Troy, 'horse' as the animal) cannot infer the meaning 'hidden malicious program' without that cultural knowledge. Although many languages use the same metaphor, the mapping from the literal words to the technical sense is idiomatic and not compositionally predictable for B1 learners.

Etymology

Trojan horse comes from an old story: Greek soldiers hid inside a big wooden horse that looked like a gift, and the people of Troy brought it inside their city walls. That's why a 'trojan horse' today means something that looks helpful but actually hides danger, like a program that secretly harms your computer.
