拆解为in（不）+ vary（变化）+ ably，助记‘不变地’
invariably 是中性词，通常用于正式和日常书面语及口语，表示‘总是’、‘无一例外地’。
Only 'variably' rhymes with 'invariably' (both have /ˈvɛriəbli/). Other words ending in -ably like 'inevitably', 'reliably', 'probably', 'comfortably', 'remarkably' have different stressed vowels or consonant clusters, so they do not rhyme exactly. Be careful not to confuse the spelling patterns.
