Another example: Search algorithms rank pages by usefulness.
Collocations: the algorithm · algorithm for · learning algorithm
Synonyms: formula, procedure (computer sense), system

privacy /ˈprɪvəsi/ noun C1 Technology

Antonyms: publicity, exposure
Word family: private (adj) · privately (adv)
⚠ Common mistake: American pronunciation often 'PRY-vuh-see' (first syllable like price) — both forms are heard. Privacy policies are the internet's least-read literature.

Register: Neutral to formal — digital life essential.

🗣 In spoken American English: IT's saddest sentence: 'The network is down' — and everyone's day stops.
Register: Neutral — tech and career essential.
breakthrough /ˈbreɪkθruː/ noun C1 Technology
