"Terminus Technicus"
The use of the Latin phrase terminus technius ('technical term') in linguistics and literature is latently semi-ironic, in that rendering the easily understandable English "technical term" in Latin with the more difficult, and to many readers exclusive, Latin equivalent "terminus technicus" itself illustrates how technical jargon and foreign loanwords narrow the semantic focus of a term. Another example is the Turkish word caïque, a word for a wooden fishing boat, which is found in Russian as kaik (Cyrillic каик) and refers not just to any wooden boat, but the usage of the boat to Russian travellers when found as a private ferry-taxi on the Bosphorus river. In other words, the idea that the boat is ferried by an Ottoman Turk ferryman is part of the exotic "Turkishness" of the word to the Russian 19th Century traveller.
