The author’s lexicon – The Language of Winnicott – has proved to be the definitive comprehensive guide to Winnicott’s thought since it was first published in 1996, Winnicott’s centenary Year. The twenty-two entries represent the major conceptualisations in Winnicott’s theories and take the reader on a journey through his writings that span from 1931 to 1971. Thus the volume is an anthology of Winnicott’s writings. This new edition expands on each original entry predicated on the author’s research discoveries, including archival material, over the past decade.
