The Virtual Linguistics Campus Repository VLC202 Historical Linguistics. It introduces you to the principles of language classification and language change and is thus the prerequisite for further courses, for example, for our course VLC203 The History of English. Let's see how you can use VLC202. If you have an account on the Open Educational Resources VLC website, which is of course free, accessing the repository is simple.

A click on the bottom of the VLC202 tile leads you to the repository start site, where you have access to all modules starting with the content description and the preliminary section with advice and help on how to use the units. And here are the current content units of VLC202. The first part goes way back in time and discusses the origin of man and the evolution of language. It shows how formal languages can be reconstructed and takes a special look at Indo-European. Part two is truly linguistic in character. It shows how languages can be classified, how they change, and it discusses and exemplifies the various types of change from phonology to semantics. How these changes influence the central grammatical options of a language is illustrated on the basis of the last unit present a English subject and object selection. This list of units is growing, updated and quality assured on a regular basis. And our teaching and learning concept, well, studying online on the virtual linguistics campus simply means go through each unit at your own pace, tick off an activity you have worked through and make use of as many VLC options as possible. And if you don't know what to do first, use the how to proceed options at the beginning of each content section.
