语域：mixed 常见场景：industrial abrasives、geology and mineralogy、nail care products 该词为技术性名词，通常出现在矿物学、工业研磨材料等较正式的专业语境中；日常英语中普通人对这个词的接触多来自“emery board”（指甲锉）等日用品名称，单独使用频率不高。因此注册语体介于正式与中性之间，需根据语境判断。
真正与 emery /ˈɛmɝi/ 押韵的常见词只有 memory /ˈmɛmɚi/。注意 celery /ˈsɛlɚi/、battery /ˈbætɚi/、nursery /ˈnɜrsɚi/、delivery /dɪˈlɪvɚi/、stationery /ˈsteɪʃəˌneri/ 虽然都以 -ery 结尾，但发音不同，勿混淆。
