The word 'naughty' is used to describe someone, often a child, who behaves in a way that is mischievous or disobedient. This behavior can be playful and harmless but may also involve teasing or breaking rules. While 'naughty' suggests a sense of fun and light-heartedness, it generally implies that the person knows they should not be acting that way.
The word 'naughty' comes from the Middle English word 'naughty', which originally meant 'having naught' or 'being nothing'. It evolved to imply moral deficiency or being bad. The term 'naught' itself is derived from the Old English 'nawiht', meaning 'nothing'.
