What is the Portuguese word for joy?

The Portuguese equivalent of the English Word 'congratulations' is the following: felicitações. The Portuguese pronunciation is the following: feh-LEE-see-tah-SOYSH. The letter 'c' with the tail tells you that the sound always is the sound of 's', as in 'simple'. The accent over the 'o' tells you that the sound always is more nasalized than a regular 'o'.
