A libretto for any opera, including Aida, is the creation of the words to sbe sung. If it is sung AND spoken, it is generally considered a musical or an operetta. The voices sing what the composer wrote in terms of music, but the poetry or words that tell the story are based on the librettist's work. In the case of Aida, A. Ghislanzoni was the librettist and the libretto was written in Italian. Someone else has translated the words into English - that person may or may not consider themselves a librettist - they may be a foreign language translater.
A librettist writes the story of the play, opera or musical. The librettist may also be the lyricist, too, but more often is not. The composer writes the music. The lyricist writes the words of the songs. The lyricist may also be the composer, the librettist, or just the lyricist. Most commonly, they are three separate people, but there are many exceptions.
Based on a novella by Prosper Mériméé, the libretto was written by Henri Meilhac and Ludovic Halévy.
The librettist is the "lyricist", the person who writes the "lyrics and dialogue" in an opera. Think of a contemporary songwriting team: "Music by Richard Rogers; Lyrics by Oscar Hammerstein".
Così fan tutte is an opera buffa by Wolfgang Amadeus Mozart with libretto written by Lorenzo da Ponte.
The composer writes the music and a librettist writes the words. For instance, Mozart wrote the music for 'The Marriage of Figaro' and Lorenzo da Ponte wrote the libretto, based on the play by Beaumarchais.
Wolfgang Amadeus Mozart composed the music and Lorenzo da Ponte was the librettist for the opera Cosi fan tutte (note the spelling of the last word :)The title means something like "That's what they all do" where the "they" is feminine (that's why the word needs the "e" ending rather than the "i", which would be masculine). Thus, "That's what all women do" :)
