Emanuele_P added a note to page 18 in the work 080416_Centro_Storico_1C_Bildergeschichte_IT in SMS collection, saying “c'era (1st line): the student wrote it without separating the article from the noun (cera). That should be an orthographic error. It's difficult to mark it though because of the apostrophy, which aumatically separates the two words.”
