The purpose of this study is to investigate lexical bundles used by EFL Korean learners in their spoken language. Lexical bundles, defined as continuous sequences of words, have been considered as the building blocks of language, reflecting psycholinguistic effectiveness, disciplinary variation, and natural language use. The spoken language of Korean learners is analyzed using the BUFS Learner Corpus of Spoken English (BUFS-LCSE), with a focus on grammatical structures and functions. For data analysis, 4-word lexical bundles extracted from BUFS-LCSE are compared with those of native speakers (LOCNEC). The results indicate that the grammatical and functional patterns differ from those of native speakers. The most frequently used categories in the grammatical structures are "subject + verb" and NP (Noun phrase). In terms of functional use, Korean learners have their own way of delivering messages, emphasizing a clear stance. These unique patterns do not necessarily indicate errors or mistakes but rather represent communication diversity within English as a Lingua Franca (ELF) from a pedagogical perspective. Therefore, Korean learners can use these results to expand their repertoire of lexical bundles based on real-life conversations rather than classroom-oriented learning.
