Spoilt and spoiled are two forms of the past tense of the verb spoil, which means to damage something, ruin it, or treat someone with too much care. Both forms are correct, but they differ by region and usage. The confusion happens because English has two systems:
British English and American English, and each prefers a different form. Many learners also struggle because both words can describe food gone bad, overindulged children, or ruined plans. In this guide, you will learn the correct usage, differences, and how to choose the right form with confidence.

Both forms mean the same and are used as past tense and past participle of the verb spoil.
The Origin of Spoilt or Spoiled
The verb spoil comes from Old French “espoillier,” meaning to plunder or strip away. Over time, it entered English and developed two past forms: spoilt and spoiled.
In early English, many verbs had irregular forms like dreamt, learnt, and burnt. These forms stayed strong in British English.
Later, American English moved toward regular verb forms by adding -ed, making words like spoiled, learned, and burned more common.
Both forms exist today, but their usage depends on regional preference and writing style.
