Hocus pocus (magic) derived from the Protoslavic word "kusiti", which is itself derived from Gothic "kausajn" meaning "to try", "to attempt". This may indicate that the wording belongs to the alchemy kitchen and court of Rudolf II, Holy Roman Emperor (1552 – 1612). Also, "hocus" may mean "to cheat" in Latin or a distorted form of the word "hoc", "this". Combination of the two words may give a sense, especially both meanings together "this attempt/experiment" and "cheated attempt/experiment". According to the Oxford English Dictionary the term originates from "hax pax max Deus adimax", a pseudo-Latin phrase used as a magical formula by conjurors.
Referring expression reference. Some of these are discussed from the perspective of linguistics in Lyons (1977, vol. I: chapter 7); Cann (1993: chapters 9 and 10); Saeed (1997: chapters 2, 7, 11). There is a vast literature on the topic in philosophy. Referring expression generation (REG) is the subtask of natural language generation (NLG) that receives most scholarly attention. While NLG is concerned with the conversion of non-linguistic information into natural language, REG focuses only on the creation of referring expressions (noun phrases) that identify specific entities called "targets" by describing their attributes that are most distinct from those of the "distractors".
