This corpus-based study examined whether Korean learners of English and L1 English writers differ in their written use of - and -initial content words. The study analyzed the Gachon Learner Corpus and LOCNESS, using relative proportions of orthographically defined initial-letter tokens and essay-level lexical frequency based on SUBTLEX-US. Korean learners showed lower proportions of both - and -initial content words than L1 English writers, and the between-corpus difference was larger for than for . However, a whole-alphabet comparison showed that several other initial letters also exhibited between-corpus differences of comparable or greater magnitude. Mixed-effects modeling showed a significant Corpus × Letter interaction, which remained after mean-centering lexical frequency. At the same time, the findings do not establish a direct causal relationship between phonological difficulty and lexical choice, because the study did not directly measure phonological processing, lexical access, or individual learners’ perception and production of /l/ and /r/. The results are therefore interpreted as evidence of corpus-level differences in written lexical distribution, rather than as direct evidence of contrast-specific phonological avoidance.
