diatechnical

According to Hausmann (1977, Ch. 8), lexically relevant units can receive — typically by means of labels or usage notes — any or all of the following types of diasystematic marking: diachronic (e.g. archaic, neologism); diatopic (e.g. American English for elevator 'lift', British English for loo); diaintegrative for foreign borrowings used in English (e.g. German for Weltanschauung); diastratic (e.g. informal for loo, formal for perambulator); diaconnotative (e.g. from Webster's Ninth New Collegiate Dictionary (W9), often used disparagingly for dyke); diatechnical (e.g. law for tort, anatomy for clavicle; diafrequential (e.g. rare); dianormative (e.g. substandard for ain't).

In order to apply linguistic and semiotic analysis to conquering the territory of the new media, it is suggested that the sociolinguistic model be integrated with a fifth axis of variation, the diatechnical axis.
