Here is a clear explanation for the position of "stesso" : http://italian.about.com/library/fare/blfare129a.htm
Nouns and adjectives have to agree in gender and number, but confusingly that doesn't mean that they end in the same letter.
Colore is masculine singular. Stesso is masculine singular. That means that they agree in gender and number. Stesse is actually feminine plural.
lo stesso colore (masculine singular)
gli stessi colori (masculine plural)
la stessa casa (feminine singular)
le stesse case (feminine plural)
"Stesso" as an adjective = same
"Stesso" as a pronoun = self
Can someone explain the reasoning behind the structure of this sentence? Ho dipinto io stesso dipinto. I understand it means “I painted this painting myself” but I don’t understand why “io” is after dipinto and the use of “stesso”. Thanks!
this sentence doesn't work like this. an article is missing
it could be:
ho dipinto LO stesso dipinto
in this case that means that someone looking at a painting is telling that he painted the same subject
ho dipinto io stesso IL dipinto
in this case someone is assuring that he personally painted the paint they were talking about
Io stesso is a construction meaning "exactly me" "me personally"
