语境与语域Context & Register
语域：neutral 常见场景：chemistry laboratory、metal foundry 作“坩埚”讲时属于中性技术用语，通常出现在化学实验室、冶金或铸造等专业场景，日常口语中很少用到。
发音与拼写Pronunciation & Spelling
possible、responsible、accessible、sensible、invincible 都以非重读的 /səbəl/ 结尾，与 crucible（/ˈkrusəbəl/）词尾读音相同；其中 invincible 还和 crucible 一样写成 -cible。不过它们重音位置不同，所以不押韵。credible 是形近词：虽然也以 -ible 结尾，但词尾读 /dəbəl/，不是 /səbəl/。
