«Тут» как показатель темпоральной близости

While space-time metaphor is a source of regular prepositional and adverbial polysemy in many languages, spatial deictic words develop temporal meanings much more rarely. However, space-time metaphor in deixis is not as exotic as it might seem, as demonstrated by the Russian spatial proximity marker tut ‘here,’ which develops a meaning of temporal proximity. Its meaning, though, is different from the meanings of classical deictic markers of temporal proximity, such as sejchas ‘now.’
