联想：steady（稳定）+ fast（牢固）→ 稳如磐石地坚持，即“坚定不渝”。注意 fast 此处不是“快”，而是“牢固”。
语域：formal 常见场景：正式写作与演讲、文学或修辞性表达 steadfastly 多用于正式或书面语境，表示‘坚定地、不动摇地’，比较常见于演讲、正式文稿或文学性表达；日常口语中较少使用，常用 firmly 或 determinedly 来替代。
发音说明：'steadfastly' 读作 /ˈstedfɑːstli/，重音在首音节。'steadfast' 与其拼写前半部分完全一致，读作 /ˈstedfɑːst/；'steadily' 以相同的 /sted/ 开头，并同样以 /li/ 结尾。'fast'、'past'、'last' 的元音加尾音 /ɑːst/ 与目标词中 -fast 部分的读音一样，但由于重音位置不同，它们与整词并不押韵。注意 'breakfast' 虽然拼写中有 'fast'，读作 /ˈbrekfəst/，'a' 弱化为 /ə/，是典型的形似音异词。
