Bilingual learner dictionaries occupy a complex role in pedagogical lexicography, as they must combine the meaning-explanation function of monolingual dictionaries with the cross-linguistic mapping function of bilingual dictionaries, while supporting L2 vocabulary acquisition. A key aspect of this complexity lies in the microstructure of annotation-type entries, which extend basic translations with grammatical, pragmatic, cultural, collocational, or example-based information. Despite their importance, these microstructural features remain underexplored in metalexicographic research. This study presents a corpus-based analysis of annotation-type entries from eight bilingual learner dictionaries across six language pairs. Using a nine-component annotation-type feature (ATF) framework, 960 entries were analyzed to identify patterns in frequency, distribution, and structure. The findings show that example-based (ATF-EX, 89.4%) and grammatical annotations (ATF-GR, 82.1%) are nearly universal, while cultural (ATF-CU, 32.0%) and visual annotations (ATF-VI, 12.0%) are relatively limited and dependent on language pairs. Differences were also observed in collocational and pragmatic annotations across proficiency levels. Based on these results, the study proposes a hierarchical model of annotation depth and highlights its implications for bilingual learner dictionary design, SLA-oriented lexicography, and under-resourced language pairs such as Uzbek–English.
