Facebook and Types of Communication
Klemperová, Aneta ; Janovec, Ladislav (advisor) ; Holanová, Radka (referee)
This text deals with specific communication features of Czech Facebook users. The work is focused on written way of expression and explains it in all linguistic disciplines. The aim of this thesis is to record mainly those expressions that are really typical of Facebook writings. Theoretical part is supplemented with concrete examples that appear on Facebook and it is testified by findings and theory about this type of written communication. We can come to the conclusion that Facebook users often do not observe the rules of using dashes, on the other hand they use frequently exclamation marks and question marks. Users often multiply punctuation marks, vocals and consonants. In lexicology we can find many expressive words, argot, and English words that make the writing original and special. Non- standard suffixes are other proofs that writing on Facebook is similar to communication in common speech.
