The slur of A, despite the fact that it begins from the 3rd or 4th semiquaver in bar 33, is certainly to be interpreted as embracing the entire 4 bars. In FE (→GE,EE) the slur in bar 33 was omitted, which is a patent error (in FE the bar is at the end of the line). Although Chopin did not add the slur in bar 33 while proofreading FE, he included sempre legatissimo. However, according to us, this indication does not have to be considered only as a substitute of the slur, which in fact does not limit to determine just the articulation.
