Jean Margaret Aitchison (born 3 July 1938)[1] is a Professor Emerita of Language and Communication in the Faculty of English Language and Literature at the University of Oxford and a Fellow of Worcester College, Oxford.
[3] Aitchison earned her MA from Cambridge, and an AM from Radcliffe College at Harvard.
[5][6] In 1996 she gave the BBC Reith lectures on The Language Web.
[8] In Aitchison (1987), she identifies three stages that occur during a child's acquisition of vocabulary: labelling, packaging and network building.
These stages are discussed in detail in surveys of theories of vocabulary acquisition such as Milton & Fitzpatrick (2014).
