The term, "language idiosyncrasies" can generally be defined as what an individual typically says that becomes part of his or her personality. In doing so, this language behaviour can either positively or negatively impact communication. Based on this premise, the current study sets out to examine the occurrences of language idiosyncrasies in second language (L2) communication, particularly at the point when communication strategies (CSs) were employed to overcome communication problems. By employing non-participant observations of real university admission interviews, this study departs from the other studies related to CSs which involved non-authentic, simulated environments. The observed interview sessions were conducted in the English language involving 29 Malay candidates from 20 interview sessions. These sessions were video-recorded before the raw data were transcribed. The results revealed some occurrences of language idiosyncrasies in candidates' utterances hence, supporting Paribakht's (1985) research finding that speakers exhibited idiosyncratic patterns in the realization of communication strategies. The results also concurred with the findings of past studies on the influence of speakers' L2 proficiency level on their use of CSs. As all participants were Malays communicating in an English speaking context, issues on cultural values added to the richness of the data and will also be discussed. While the findings may not be generalizable to all populations, it is hoped that this study will inform curriculum developers of language idiosyncrasies of Malay students, who form the bulk of the student population in Malaysia, so that awareness may be raised and appropriate interventions may be introduced.
