Willingness to communicate (WTC) was originally conceptualised for first language acquisition, and seeks to demonstrate the probability that a speaker will choose to participate in a conversation of their own volition (McCroskey & Baer 1985, cited in MacIntyre et al., 1998). Traditionally, it was seen as a fixed personality trait that did not change according to context. However, McCroskey and associates suggested that it is in fact a situational variable that will change according to a number of factors (how well the speaker knows the interlocutor(s), number of interlocutors, formality, topic etc.).
