This study investigated grammatical difficulty from the perspective of second language (L2) learners in relation to their overall L2 proficiency and L2 performance and knowledge. The design included the administration of a student questionnaire, an interview, a proficiency test, and oral production and metalinguistic tasks. The proficiency test and questionnaire were administered to 277 university-level Chinese EFL learners in Taiwan. The questionnaire explored learners’ perceptions of grammatical difficulty of 20 English grammar features. Thirty of the students who completed the questionnaire met with the researcher individually to complete a grammatical difficulty ranking activity, 2 grammar exercises and 2 stimulated recalls, all of which aimed to further explore why the learners considered the selected features to be more (or less) difficult for them to learn. The oral production tasks were administered to 27 of the students who completed the questionnaire. The metalinguistic task was administered to 185 of the students who participated in the questionnaire survey. The questionnaire results indicate that, overall, the participants did not perceive the 20 target features to be difficult to learn. Notwithstanding, the ranking results of the questionnaire suggest that learners’ perceptions of grammatical difficulty are based on whether the rules to describe the formation of language features are easy or difficult to articulate. The qualitative results show that the learners’ perceptions of grammatical difficulty were influenced by several factors including their L2 knowledge, L2 grammar learning experience, and L1 knowledge, all of which were examined with reference to syntactic, semantic, and/or pragmatic levels. In terms of the relationship between learners’ perceptions of grammatical difficulty and their overall L2 proficiency, results show that learners’ perceptions of grammatical difficulty do not vary at the syntactic level, but that there is some variation at the pragmatic level. Regarding the relationship between learners’ perceptions of grammatical difficulty and their L2 knowledge, results suggest that learners’ perceptions of grammatical difficulty vary according to their implicit/explicit knowledge of the features in question; at the explicit knowledge level, the feature perceived to be less difficult to learn is used more accurately, while at the implicit knowledge level, this is not the case.
