Analysis of information sources in references of the Wikipedia article "Foreign-language influences in English" in English language version.
Percentages are often quoted for the proportions of the vocabulary of modern English that are borrowed from French, Latin, Scandinavian languages, etc. As discussed in chapter 1, such percentages must be approached with extreme caution. Firstly, we have to bear in mind that such figures can only refer to a particular period: the proportions in contemporary English will not at all be the same as those in sixteenth- or seventeenth-century English, for example. Secondly, we must consider whose English we are talking about, as discussed in section 1.5. Thirdly, once we have decided which registers, varieties, etc. we want to take into account, we have the practical problem of arriving at a wordlist. Fourthly, once we have our wordlist, we have the problem of assessing and classifying etymologies, i.e. deciding which words are borrowed and which are not. This last problem is a major concern of this book.
