IPA: /ɪtˈsɛlf/
KK: /ɪtˈsɛlf/
A pronoun used to refer back to the subject of a sentence, often for emphasis or to indicate that something is the same as what has already been mentioned.
The cat scratched itself while playing.
Itself originates from Old English 'itself', which is a combination of 'it' (a pronoun used to refer to a thing previously mentioned) and 'self' (from Old English 'seolf', meaning one's own person). The word 'itself' refers to the very thing or person that has been mentioned, emphasizing its own identity.
Think of 'it' as referring to a specific thing and 'self' as emphasizing that thing's own identity — that's why 'itself' means the very thing being talked about.
