Terminology has started to explore unbeaten paths since Wüster, and has nowadays grown into a multi-facetted science, which seems to have reached adulthood, thanks to integrating multiple contributions not only from different linguistic schools, including computer, corpus, variational, socio-cognitive and socio-communicative linguistics, and frame-based semantics, but also from engineering and formal language developers. In this ever changing and diverse context, Terminology offers a wide range of opportunities ranging from standardized and prescriptive to prototype and user-based approaches. At this point of its road map, Terminology can nowadays claim to offer user-based and user-oriented, hence user-friendly, approaches to terminological phenomenona, when searching, extracting and analysing relevant terminology in online corpora, when building term bases that contribute to efficient communication among domain experts in languages for special purposes, or even when proposing terms and definitions formed on the basis of a generally agreed consensus in international standard bodies. Terminology is now ready to advance further, thanks to the integration of meaning description taking into account dynamic natural language phenomena, and of consensus-based terminology management in order to help experts communicate in their domain-specific languages. In this Handbook of Terminology (HoT), the symbiosis of Terminology with Linguistics allows a mature and multi-dimensional reflection on terminological phenomena, which will eventually generate future applications which have not been tested yet in natural language. The HoT is linked to the Handbook of Translation Studies, not in the least because of its interdisciplinary approaches, but also because of the inevitable intertwining between translation and terminology.
