Future directions and conclusion
The purpose of this chapter has been to point out areas of research that might make us look again at research that has already been done for inspiration for new areas of research, for ideas for expansion, or for consideration for replication. There has been a wide range of interesting and effortful work in vocabulary for academic and specific purposes, by people working alone or in research groups, and in many areas of the world. This book has been motivated by these people, their approach to research, their suggestions for future research and their desire to find out more about vocabulary in ESP to better serve the needs of learners and teachers. I hope this book has identified possible gaps in the field of specialised vocabulary in ESP and provided some suggestions for future research. There is much work to be done, and there are many good reasons to do it.
