Abstract：Abstract: This paper highlights the value of genre-informed phraseology to the compilation of EAP dictionaries. A case study is presented to illustrate the establishment of macrostructure and the justification of the microstructure of the headword ‘delivery’ on the basis of a one-million-word corpus of international medical research articles. The macrostructure, namely the selection of headwords and the overall size of a dictionary, is facilitated by the keyword method (i.e. the comparison between medical and general English) in corpus research; microstructure-wise, the phraseological analysis is adopted to identify the different senses of ‘delivery’ and the senses arranged by the decreasing order of frequency in the entry. Meanwhile, ‘the whole sentence definition’ demonstrates the most typical patterns and meanings of the headword. The commonest phrases and authentic sentences containing the headword are provided as well. On top of all these, the sub-discipline preference and discourse move distribution of the headword are integrated to the definition, examples, etc. This latter point adds a generic dimension to the phraseological scheme of dictionary writing, thereby accommodating the EAP learning needs.
