H?r hansı bir elmin inkişafı insanların praktik f?aliyy?ti ehtiyaclarından doğur v? bu ehtiyaclarla mü?yy?nl?şir. H?r hansı bir elmin tarixi göst?rir ki, elmd? ?vv?ll?r t?tbiqi m?s?l?l?r hakim olmuş v? elm inkişaf etdikc? ümumil?şm?l?r aparmaq m?qs?dil?, h?r d?f? eyni t?crüb?l?r? qayıtmamaq üçün onlardan n?z?ri bölm? ayrılmışdır. Dilçiliyi ş?rti olaraq "elmi dilçilik" v? ya “dilçilik n?z?riyy?si” iki gism? bölürl?r. Görk?mli alim ?.R?c?bli d? bu m?s?l?y? öz münasib?tini bel? bildirir: “Elmin t?tbiqi v? qeyri-t?tbiqi (n?z?ri) bölm?l?ri arasındakı s?rh?d olduqca ş?rtidir v? çox vaxt t?tbiqi bölm?nin harada bitdiyi, n?z?ri bölm?nin haradan başlandığını mü?yy?nl?şdirm?k mümkün olmur. Ancaq bir şey şübh?sizdir: bütün zamanlarda ictimai ehtiyac v? sosial ş?rait elmin t?r?qqisini, inkişafını stimullaşdırmışdır”
The development of any science comes from the needs of people's practical activity and is determined by these needs. The history of any science indicates that prior to application of science in the field of science, the theoretical partition was separated from them to avoid the same experiences every time in order to make generalizations as science progresses. The linguistics is conditionally divided into two categories: "scientific linguistics" or "linguistic theory". The distinguished scientist Rajabli also expresses his position on this issue: "The boundary between the application of science and the non-applied (theoretical) divisions is a precondition, and it is often not possible to determine where the unit of the application unit is starting, where the theoretical unit originated. But nothing is doubtful: social needs and social conditions at all times have stimulated the progress and development of science.
