Children’s language datasets

It's vital for children to be able to access language support at their level, using age-appropriate vocabulary and definitions, and examples from contexts they will recognise. At Oxford, we produce a range of dictionaries that build and grow with children’s levels of vocabulary and comprehension, each catering to a specific age range and stage of learning.


We use our expertise in children’s language to identify which words to include for each age and to ensure that the definitions use words children will know or can look up in the same book. We also make sure the information supporting those words – the example sentences, pronunciations, grammar information, usage and word origin notes – are accessible. No vulgar, offensive, or sensitive vocabulary is included in our datasets.


The below examples demonstrate how the definition of the word air evolves through different levels of our children’s dictionaries and the Oxford Dictionary of English for adults:
