All authors must admit to a dependence on the work and wisdom of others. We are no exception. We owe a huge debt of gratitude to all the publications and reference resources that we have consulted and adapted to produce the educational materials on this website. It would also have been quite impossible to have produced those materials without adapting a variety of authentic resources that we have regularly referred to. While every effort has been made, it has not always been possible to identify and cite the sources of all the material used or to trace all copyright holders. We will be happy to omit any contents or include any appropriate acknowledgements when they are brought to our notice. For further enquiries and suggestions, please reach us on Instagram.


The word family entries on this website list all possible derivatives, compounds, and related combinations from both non-learner’s (Lexico for C2+ word families) and advanced learner’s dictionaries (CALD and OALD for C1–C2 word families). Information about word origins is selected from The Oxford Dictionary of Word Origins, Lexico by Oxford, Online Etymology Dictionary, which, along with other authentic resources, are also adapted for educational purposes.
