The slur of A is written over the notes and it embraces the entire motif, together with the minim. It is also poorly visible due to the ending ink and the upcoming word acceler. It explains the absence of the slur in FE, as its oversight by the engraver or even considering it to be deleted by the overwritten indication is highly likely. The slur was completed in the remaining editions on the basis of analogy with similar bars earlier and bar 173. In the main text we give the slur in this form – under the notes and embracing the semiquavers only, as Chopin, while writing A, probably erroneously wrote the original form of this sign. It is proved by the clear slur in the next bar, as well as the notation of bar 20, in which the composer deleted the longer slur over the stave, replacing it with a shorter one under the notes.
