It is probable that you will use terminology in your research which has been defined and used in a variety of ways by different researchers in your field. This terminology is likely to encompass the labels given to concepts and theories, such as those mentioned in the section above, as well as more concrete nouns, such as 'social worker' or 'diabetes'. It is important that you do not assume a common agreement about the meaning of all the words and phrases that you include. You should therefore introduce your reader to the variety of ways a term has been defined and interpreted and/or make it clear how you will be using the term.
