Phatic expression
In linguistics, a phatic expression (, ) is communication which serves to establish or maintain social relationships rather than to impart information. Phatic expressions are a socio-pragmatic function and are used in everyday conversational exchange typically expressed in situational instances that call for social cues. They can include social pleasantries that do not seek or offer information of intrinsic value but can signal willingness to observe conventional local expectations for politeness. Other uses of the term include the category of "small talk" (conversation for its own sake) in speech communication, where it is also called "grooming talking." In Roman  Jakobson's work, the 'phatic' function of language concerns the channel of communication; for instance, when one says "I can't hear you, you're breaking up" in the middle of a cell-phone conversation. This usage appears in research on online communities and micro-blogging. Purpose. Phatic communion at first appears to break Grice's conversational maxims, because it denotationally appears to give information that is unnecessary, untrue, or irrelevant. However, phatic communion plays an important role in language and has important connotational meanings that do not break these maxims and needs to be understood as an important part  of language in its role in establishing, maintaining, and managing bonds of sociality between participants, as well as creating feelings of solidarity, familiarity, and putting participants at ease History. The term "phatic communion" ('bonding by language') was coined by anthropologist Bronisław Malinowski in his essay "The Problem of Meaning in Primitive Languages", which appeared in 1923 as a supplementary contribution to "The Meaning of Meaning" by C. K. Ogden and I. A. Richards. The term "phatic" means "linguistic" (i.e. "by language") and comes from the Greek φατός "phatós" ("spoken, that may be spoken"), from φημί "phēmí" ("I speak, say"). Importance  of Context. Many expressions generally considered to be phatic ("see below") may be a genuine request for information in certain contexts. For example, in British-English, “How are you?” is a phatic expression used when greeting someone one knows, especially when a participant wants to initiate conversation. However, it can be asked sincerely, and this must be inferred from context, such as when a friend gives bad news, or tone, such falling intonation to show it as a genuine question (as is with w/h-word questions), or speaking more quietly. Authenticity of the question can also be emphasised by  the addition of the word “feeling” (“How are you feeling?”). Phatic expressions in various languages. Danish. Danish has several phatic greetings: Some phatic greetings are only used in writings such as letters, e-mails and speeches read aloud: Some greetings like "hej" can be used throughout the day. Some are more specific, and the specific time of when to switch to the next greeting can vary from speaker to speaker. Time-specific greetings include "Godmorgen" ('good morning'), "God formiddag" (literally 'good pre-noon'), "Goddag" ('good day'), "God eftermiddag" ('good afternoon'), "Godaften" ('good evening'), and "Godnat" ('good night'). Ways of saying  thanks include "tak "'thanks', "tak skal du have" 'thanks shall you have', "mange tak" 'many thanks', 'thousand thanks', "tak for det" 'thanks for that' and "jeg takker" 'I thank'. A thanks can be answered with "selv tak" 'self thanks' or "det var så lidt" 'it was so little' (referring to the small amount of work that had to be done). Other phatic expressions include "Held og lykke" ('luck and fortune'), equivalent to the English "good luck", and "Knæk og bræk" ('crack and break') which has the same meaning as "good luck" similar to the English expression "break a leg", mostly  used by hunters, fishers, and theater crews. English. "You're welcome", in its phatic usage, is not intended to convey the message that the hearer is welcome; it is a phatic response to being thanked, which in turn is a phatic whose function is to acknowledge the receipt of a benefit. Similarly, the question "how are you?" is usually an automatic component of a social encounter. Although there are times when "how are you?" is asked in a sincere, concerned manner and does in fact anticipate a detailed response regarding the respondent's present state, this needs to be pragmatically  inferred from context and intonation. Example: a simple, basic exchange between two acquaintances in a non-formal environment: Or: In both dialogues neither speaker expects an actual answer to the question but rather it is an indication that each has recognized the other's presence and has therefore sufficiently performed that particular social duty. Icelandic. There are several phatic greetings in Icelandic differing in formality: Thanking: Japanese. In Japanese, phatic expressions play a significant role in communication, for instance the backchannel responses referred to as "aizuchi". Other such expressions include the ubiquitous "Yoroshiku onegaishimasu" ("please treat me well", used before  starting work with someone), "Otsukaresama desu" (lit. "you must be tired", closer to "thank you for your hard work"—used for leave-taking and sometimes as a greeting) and "Osewa ni natte imasu" ("thank you for your support"). Mandarin Chinese. In China, the phatic expression "吃饭了吗" "have you eaten?" is equivalent to English speakers "how are you?" Food culture is important in China and thus inquiring if one is well-fed implies the speaker's desire to know if you have this basic need met. This expression is most often used by older members of society towards younger persons. Persian. Taarof  is a complex set of expressions and other gestures in Persian society, primarily reflected in the language. Welsh. In Welsh the general phatic is a regional and colloquial version of "sut mae?" ("how is?"). The general pronunciation in southern Wales is "shw mae" and in the North, "su' mae". The usual answer is "iawn" (OK) or, "iawn, diolch' (OK, thanks), or maybe the more traditional, "go lew" (quite good), "go lew, diolch" (quite good, thanks). "Many native-speakers don't answer like this. but simply say, "shw mae?" or "su' mae?" in response." The use of "sut mae" phatic has  been used as a Welsh language campaigners to encourage Welsh-speakers to begin conversations in Welsh, and for non-fluent speakers to "give it a go". Shwmae Sumae Day was held for the first time in 2013 and is held annually on 13 October. In fiction. Phatic expressions are often created by authors, particularly in science fiction or fantasy, as part of their worldbuilding. Non-verbal phatic expressions. Non-verbal phatic expressions are used in nonverbal communication for emphasis or to add detail to the message that a person conveys or expresses. Common examples of these are smiling, gesturing, waving , etc. According to Dr. Carola Surkamp, professor at University of Cologne, non-verbal phatic communication can be expressed with involuntary physical features such as direction of gaze, blushing, posture, etc. and that these have a vital function in regulating conversation. Online phatic expressions. Phatic expressions are used on different communication platforms on the internet such as social media networks where certain platforms require and prompt certain actions to be made between users to communicate or implicate certain messages between people without direct utterances. Examples for this would be: 'likes', comments/replies, shares/reblogs, emoji use, etc. These "phatic posts" as  Radovanovic and Ragnedda like to call them, are again used with a social function of social communicative upkeep with the primary function of expressing social connection, relationships between users, and recognition of coparticipants.
