The application of linguistic analysis to editing may serve three purposes. First, it can provide insights into the nature of linguistic structure. The editing process often results in minute changes which put language structure under the microscope in a way which usually occurs only in the arm-chair linguist's intuitions. This motivation is purely internal to the discipline of linguistics. Although it applies linguistic analysis to an object to which it is not normally applied, it is not applied linguistics in the sense of addressing issues beyond the discipline itself
