1.形容詞B1
釋義

不規則

文法變化不依標準規則的

An irregular word does not follow the standard patterns that most words of its type follow when changing form — for example, a verb that does not add '-ed' for the past tense, or a noun that does not add '-s' for the plural.

例句

The verb 'go' is irregular because its past tense is 'went', not 'goed'.

動詞「go」是不規則變化,因為它的過去式是「went」而非「goed」。

irregular verb: past tense not formed with -ed

Children often struggle with irregular plurals like 'mice' and 'children'.

兒童經常在學習不規則複數(如「mice」和「children」)時遇到困難。

irregular plural: no -s ending

  • unofficial

    broader; not specific to military contexts

反義詞

文法句型

irregular + noun (forces/troops/soldiers/fighters)

用法筆記

Often used before a noun ('irregular forces', 'irregular troops'). The standalone noun form 'irregulars' refers to these fighters but is less common. 'Guerrilla' is a related but narrower term referring to a specific type of irregular fighter using hit-and-run tactics.

常見錯誤

He joined an irregular group' (meaning any unofficial organisation).
He joined an irregular military unit.
💡This sense is specific to armed fighters and military contexts, not general unofficial groups.
