We know that native speaker is someone who has spoken a particular language since they were a baby, rather than having learned it as a child or adult, but what is Philologist? Philology, (from Ancient Greek φιλολογία (philología) ‘love of word’), in definition, is the study of language in oral and written historical sources; it is the intersection of textual criticism, literary criticism, history, and linguistics with strong ties to etymology. According to this definition, Philologist is a a person who specializes in philology, the study of literary texts and written records, or (especially in older use) a person who specializes in linguistics, especially historical and comparative linguistics.
The native speaker understands and “feel” his native language and express and transmits the information, ideas and feelings clearly in it, and use it as part of their identity. This leads in naturalness to their speaking and writing. The philologist focuses on studying history and politics behind the language development.
The service industry is also a place where native speakers can shine. Their ability to understand language in daily use, and to speak that language comfortably and clearly is very important.
Some other jobs where native speakers are likely to have an advantage are:
Law Enforcement
Primary And Elementary Education
Healthcare And Medicine
Counseling
Legal Affairs
Warehouse Factory And Manufacturing Work
Agriculture
None of these require a need to understand the historic use of language or to consider political factors or entomology. Instead, these jobs require a thorough knowledge of a language including the abilities to think, speak, and write absolutely fluently.
