The Oxford Advanced Learner's Dictionary (OALD) was the first advanced learner's dictionary of English. It was first published 68 years ago. It is the largest English-language dictionary from Oxford University Press aimed at a non-native audience. Users with a more linguistic interest, requiring etymologies or copious references, usually prefer the Concise Oxford English Dictionary, or indeed the magnum opus, the Oxford English Dictionary, or other dictionaries aimed at speakers of English with native-level competence.
