himself
The Italian word 'lui stesso' means 'himself' in English. 'Lui' means 'he', and 'stesso' translates to 'self' or 'same'. It's a reflexive pronoun used when the subject and the object of the sentence is the same person. Similar to English, it is used in reflexive actions where the action is performed by the subject onto itself.

He bought the gift himself.
In this sentence, 'Lui stesso' is used to stress that he made the purchase on his own, perhaps implying that this is not what would usually happen or that it was an important or significant action.
