记忆联想：wharf 和 dwarf 押韵，想象小矮人在码头上搬木箱——wharf 就是码头。
语域：neutral 常见场景：port、harbor、shipping 名词 wharf 表示“码头”，属于中性用词，通常用于航运、港口等场景。在书面语和一般口语中都可以使用，正式场合也较为合适。
真正与 wharf /wɔrf/ 押韵的常见词是 dwarf /dwɔrf/ 和 morph /mɔrf/。war /wɔr/、warm /wɔrm/、warp /wɔrp/、ward /wɔrd/ 虽然拼写上都含 war-，并且也都以 /wɔr/ 开头，但最后一个辅音不同，并不与 wharf 完全押韵。
