In this paper we argue multiphastic characteristics of linguistic phenomena caused by the inseparable relationship between the individual language system, sociohistorical factors, and our mind`s language management mechanism. We choose Spanish second-person addressing pronouns because they verify how difficult is to obtain well-purified linguistic data, which are free from sociohistorical factors. Spanish adopts several forms to refer to the person or group of people that are being addressed. Showing different distributions across Spanish speaking countries, tu, vos and usted are used as singular forms, while vosotoros/-as and ustedes are used as plural forms. Spanish speakers reinforce their solidarity through reciprocal uses of tu, vos, or both of them. They expressed their respect through reciprocal uses of usted, though until the present day nonreciprocal uses are observed in certain circumstances more in Spanish America than in Spain. We consider sociohistorical factors to explain these phenomena.
And also we analyse how an individual speaker can make additional pragmatic effects. We argue that the more complicated the language system is, the more it permits abundant and detailed expression choices on the part of the speaker.
In conclusion, to understand multiphastic characteristics of linguistic phenomena better, a holistic approach can be very helpful as we have seen in this work.
