Abstract
This paper shows the connection between emoticons and politeness in written computer-mediated communication. It studies if there are some differences in the use of emoticon between Czech and English written tweets.
The assumptions about the use of emoticons were based on the use of greetings and thanks in real, faceto-face situations. The first assumption, that welcome greeting phrase would be accompanied by positive emoticon, was correct.
But for the farewell greeting are both positive and negative emoticons possible. The results show lower frequency of negative emoticons in this context.
There were also quite often found both positive and negative emoticon in the same tweet. The expression of gratitude is associated with positive emotions.
The results show that emoticons accompany polite phrases of greeting and thanks very often both in Czech and English. The use of emoticons with studied polite phrases shows that emoticons have become an integral part of these phrases.
