Cambridge University Press released the first edition of what is now known as the Cambridge Advanced Learner's Dictionary in 1995. It carried a different name at that time, called the Cambridge International Dictionary of English.
The second edition arrived in 2003 with updated entries and revised definitions. A third edition followed two years later in 2005, incorporating new words and refining existing explanations. The fourth edition appeared in June 2008, bringing further improvements based on user feedback and linguistic research. By 2013, the press published the fifth edition, which included over 140,000 words and phrases.
The Cambridge International Corpus provided the raw data that shaped word selection across all entries. Editors analyzed millions of sentences to determine usage frequency and context. Over 140,000 words, phrases, and meanings were selected using this evidence-based approach.
Learners at CEFR levels B2 through C2 find the content most suitable for their proficiency. A dedicated 32-page Focus on Writing section supports advanced students in developing academic skills. The layout includes clear explanations tailored to upper-intermediate and expert-level users.
Cambridge University Press & Assessment began selecting a Word of the Year starting in 2015. In 2020, quarantine was chosen because lockdowns during the COVID-19 pandemic drove search activity. The following year, perseverance became the word after people sought motivation during difficult times. By 2022, homer won the title as Wordle players searched for five-letter words frequently.
