Verbal indications

b. 40-42

composition: Op. 25 No 1, Etude in A♭ major

No indication in AI & CDP

in A (→GE) & EE

in FE

..

The dim. indication could have been added in A after preparing CDP. Lack of the dashes determining the range of its indication in FE is probably a result of the engraver's inaccuracy.

b. 42-43

composition: Op. 25 No 1, Etude in A♭ major

in AI

in A (→GE), FE & EE

No indication in CDP

..

The ritenuto indication, written in AI, is certainly earlier than smorzando, which Chopin chose at the time of writing A. Minor deviations in the placement of the indication visible in FE and EE were probably created randomly and they do not influence the meaning of the indication.

b. 44

composition: Op. 25 No 1, Etude in A♭ major

No indications in AI & CDP

 & leggieriss. in A (→GE)

 & leggieriss. in FE & EE

..

Both indications –  and leggieriss. – were probably added by Chopin at the last stage of preparing the manuscript base texts for the editions. It is proven both by their absence in AI and CDP and different placement of leggieriss. in FE and EE – Chopin probably wrote this indication in this form in [FR] and [AR].

b. 47-48

composition: Op. 25 No 1, Etude in A♭ major

 in bar 48 in AI

 in A (→CDP,GE), FE & EE

..

It is worth noting that due to the different range of  hairpins, the  indication in bar 47 has a slightly different meaning in A (→CDP,GE), where it falls in the middle of diminuendo, and a different one in FE and EE, where it appears as the last dynamic indication.
