记忆提示：codeine 的发音近似中文译名“可待因”，可联想“咳嗽可待一会儿，只因吃了这药”，借此记住它是止咳镇痛药。
语域：mixed 常见场景：medical prescriptions、pharmaceutical product labels、everyday health conversations about cough or pain relief codeine（可待因）是药名，通常出现在医疗或药学语境中，如处方、药品说明和临床讨论；日常口语中比较常见于谈论止咳药或止痛药时，多用于一般健康话题，整体不算俚语或口语词。
这些词都不是 codeine 的完全押韵词。caffeine、protein、morphine、nicotine 都以 /iːn/ 结尾；protein 与 codeine 的重读元音相同（/əʊ/），但 /t/ 和 /d/ 不同，所以只是近似押韵。注意 vein 中的 ei 读 /eɪ/，不读 /iːn/；iodine 在美式英语中常读 /ˈaɪədaɪn/，-ine 不一定发 /iːn/。
