One of Garbo's trademarks is of cource her stunning voice but also her very special way accent and her imperfect English. Garbo was often amused about that. She spoke the language quite well, her misusages always minor and charming.
Garbo's friend Sam Green said: "She she turned almost every sentence into a joke on the one before. It was fascinating the way she wove her verbal tapestry. She had a real gift for language and for discovering a new word. Once she learned the word ‘unruly', she used it fifty times a day for a while and then not again for a year. She had a deep sense of irony and mimicry and of course she was a consummate entertainer.
She almost never used the words ‘I', ‘me', or ‘my'. She said that when people used those words, it meant the subject was of interest only to the speaker. It's very hard to avoid first-person pronouns, but she managed to do it day after day. It's a feat – and it's effete – but she did it as a kind of exercise in language control."
