* * * Time and diachronic characteristics:

1, the difference between range and boundary

The research object of * * * is not everything owned by colleagues, but just all the facts of each language, which can be divided into dialects and sub-dialects if necessary. On the contrary, diachronic linguistics not only has no such need, but also does not allow a clear definition. The elements it considers do not necessarily belong to the same language, but the continuation of diachronic facts and its spatial appreciation cause language differences.

2. The research objects are different.

* * * Temporal linguistics studies the logical relationship and psychological relationship among the elements that exist at the same time and constitute a system, and these elements are perceived by the same collective consciousness. Diachronic linguistics, on the other hand, studies the relationship between continuous elements that are not felt by the same collective consciousness. These elements replace each other and do not form a system.
