This article sketches how corpus linguistics—and more specifically the corpus-assisted discourse studies approach—can contribute useful dimensions to studies of language ideology. First, it is asserted that the identification of words of high, low, and statistically significant frequency can help in the identification and examination of language ideologies within corpora. The frequency of linguistic patterns and discursive representations may disclose trends in explicit representations of languages (i.e. metalanguage) and elisions where assumptions are made about the role of languages (i.e. implicit language ideologies). Secondly, collocation data can help researchers in gaining greater insight into the ways in which languages are being represented (or not) within sites identified via frequency and statistical significance. Finally, the use of dispersion plots can aid researchers to identify sites with high- and low-frequency items for closer assay. The article concludes with some of the restrictions of the corpus linguistic approach in studying language ideologies. Examples stem from a broader comparative study of French and English language ideologies in corpora of Canadian newspapers.
