Historical Linguistics is also known as “Diachronic Linguistics” involves the study of phonetical grammatical, syntactic, semantic changes. In addition, there is the possibility of identifying the process of the language reconstruction and genetic relationships. How words were they used to be pronounced in the past and how does that differ to the present? A good chunk of words is pronounced the same, but spelled differently. Where did language start? Etymological speculations of both classical and medieval times are part of the roots of historical linguistics. Examine the Greek, Latin, and Indo-European languages while studying this topic.
