The use of professional languages offers:
  • A
    longer attention span
  • B
    more precise grammar
  • C
    better communication even if professionals are not from the same field
  • D
    quick comprehension and simplified grammar


In everyday communication, there is room for misunderstandings. In order to overcome the disadvantages of everyday language, professionals in any field use technical languages which are much less subject to ambiguity and are more economical when communicating amongst themselves. This so-called professional language should be mastered by all professionals in order to allow mutual understanding and safe operations and it has some special characteristics:
  • Restricted wording: Vocabulary consists only of words that are required to express any desired information in the professional context.
  • Strict definition: In everyday language, several words are often used to describe the same or very similar concepts. When a word is adopted by professional language, no ambiguity exists as to what is meant.
  • Simplified grammar: Complex sentences are not used in favour of efficiency. For example, the ATC request “Check speed”, which replaces the sentence “Please, check if you are flying the cleared speed”. This reduces the risk of ambiguities leading to dangerous situation.
  • Neologism: New words are created which do not exist in everyday language.
  • Re-interpretation: individual words are used with a different meaning from everyday language.
