British word for spoiled

Answer 1

It's the same word. While sometimes American and British English have different slang, in this case, you may actually be referring to British spelling. The word "spoiled" is often spelled "spoilt" in traditional British orthography. Similarly, an American English word like "learned" would be spelled "learnt." But the words still have the same meaning-- only the spelling is different.

Answer 2

'Spoild' is not listed in any English language dictionary.

However, the past and the past participle of the verb spoil is spelled/spelt two ways: spoiled or spoilt.

In the UK (British-English) both spellings are used.

Both spellings are also used in the US (North American-English), but spoiled is more usual.

Answer 3

damage, demolish, blemish
