They may be one-sided, that is, contained in the utterance of only one participant in an oral communication event, or they may involve a question-response format. By themselves, routines do not usually have literal meaning, and it simply has a phatic function in conversation (aims to establish or maintain social contact, rather than conveying specific information). Many routines are based on cultural knowledge, and therefore present problems for language learners who may learn the meanings of the words but not its contextual meaning.
Native speakers possess a list of memorised routines which help their speech sound natural, and if language learners wish to achieve a sense of naturalness as comparable as possible to that of a native speaker, they must be taught common formulae and routines as part of the speaking component of a language course
