比較語言學
[编辑]比較語言學（原為比較語文學）is a branch of historical linguistics that is concerned with comparing languages in order to establish their historical relatedness. Languages may be related by convergence through borrowing or by genetic descent, thus languages can change and are also able to cross-relate.
Genetic relatedness implies a common origin or proto-language. Comparative linguistics has the goal of constructing language families, reconstructing proto-languages, and specifying the changes that have resulted in the documented languages. To maintain a clear distinction between attested language and reconstructed forms, comparative linguists prefix an asterisk to any form that is not found in surviving texts.

[编辑]Etymology is the study of the history of words: when they entered a language, from what source, and how their form and meaning have changed over time. A word may enter a language as a loanword (as a word from one language adopted by speakers of another language), through derivational morphology by combining pre-existing elements in the language, by a hybrid of these two processes called phono-semantic matching, or in several other minor ways.
In languages with a long and detailed history, etymology makes use of philology, the study of how words change from culture to culture over time. Etymologists also apply the methods of comparative linguistics to reconstruct information about languages that are too old for any direct information (such as writing) to be known. By analyzing related languages with a technique known as the comparative method, linguists can make inferences, about their shared parent language and its vocabulary. In that way, word roots that can be traced all the way back to the origin of, for instance, the Indo-European language family have been found. Although originating in the philological tradition, much current etymological research is done in language families for which little or no early documentation is available, such as Uralic and Austronesian.

[编辑]Dialectology is the scientific study of linguistic dialect, the varieties of a language that are characteristic of particular groups, based primarily on geographic distribution and their associated features. This is in contrast to variations based on social factors, which are studied in sociolinguistics, or variations based on time, which are studied in historical linguistics. Dialectology treats such topics as divergence of two local dialects from a common ancestor and synchronic variation.
Dialectologists are concerned with grammatical features that correspond to regional areas. Thus, they are usually dealing with populations living in specific locales for generations without moving, but also with immigrant groups bringing their languages to new settlements.
