inadequacy 可以想成這樣一個畫面：有一條線，畫在「必須達到」的高度上，而那樣東西就停在線的下面一點。它不是壞掉的，也不是不好的，它只是搆不到那條線。這個字可以指一樣東西搆不到，可以指一個人覺得自己搆不到，也可以指一個一個搆不到的地方。From the word’s history
Wiktionary gives inadequacy as inadequate + -cy, or in- + adequacy: in- 'not', adequate 'enough for the purpose', -cy 'the state of'. Literally, the state of not being enough for what is asked.
Wiktionary 記這個字是 inadequate + -cy，或 in- + adequacy：in- 是「不」，adequate 是「足以應付」，-cy 是「狀態」。字面就是「達不到要求的狀態」，那條線一直都在字裡。

noun · C1
A particular fault or weak point in a person, a plan or a system. In this meaning the word can be counted and usually appears in the plural.
不足之處；缺點
