The article explores the interaction of fields (reciprocity and temporality), i.e. the task posed in the functional grammar, that highlights the field of reciprocity in the field of voice. The generating model of the field of reciprocity undergoes the convergence in the process of realization in speech (from a complex sentence to a simple word) and divergence (from a word to a simple sentence and a complex sentence). In the text, the model can be a complex sentence, and a simple one, and a combination of words in the sentence members - their idiom, or a word that carries information about mutual relations. The author raises the problem of the subjective-objective nature of the functional-semantic category of temporality, which is revealed in interaction with the chronotope of the field of reciprocity. This is important for the methodology of research of functional-semantic fields and linguodidactics. The author reveals the autonomy of the subjective time of the field of mutual relations, which is fixed mainly lexically (the periphery of the functional-semantic categories). As well as the objectivity of the semantics of the grammatical center of the functional-semantic category of temporality, which is realized in speech acts of thought-speech-language activity.
