English has become a global lingua franca unlike any language before. This has led to the increased pragmatic use of English by an increasing number of non-native speakers and, consequently, English as a lingua franca (ELF) has emerged. It has become a contact language between speakers of different mother tongues which has led to the blurring of strict regulatory frameworks formerly established by native English varieties. ELF speakers use English in creative ways and influenced by their native languages and cultures and the imitation of the native speaker has been pushed to the background in favor of successful communication. In order to facilitate the examination of this new type of English, several ELF corpora have been established, two of which are used for this study. The Vienna-Oxford International Corpus of English (VOICE) and the Asian Corpus of English (ACE) are both collections of spoken interactions between ELF speakers that have the same size and rely on the same coding system and search parameters, which make them readily comparable. While these corpora have already aided in the discovery of several common features of ELF in general, this study focuses on the lexico-grammatical feature of the pluralization of mass nouns by either adding the ‘s’ or some type of quantifier in European and Asian ELF. Results show that Asian ELF speakers are less likely to pluralize mass nouns than European ELF speakers. Yet, pluralization can be found in both types of ELF and this, along with other specific, non-standard features, raises questions for English language teaching and the status of native English.
