This paper analyses the use of the discourse marker LIKE in Irish English (IrE) with respect to a speaker’s age and gender and illustrates how the International Corpus of English (ICE) can be used for fine-grained sociolinguistic analyses. The results suggest that LIKE use significantly decreases as speakers exceed their mid-thirties and that all variants of LIKE undergo changes which are, however, restricted to younger speakers. Keywords: Discourse marker LIKE; sociolinguistics; linguistic variation; language change; gender; age; ICE Ireland; quantitative analysis
