Example 1 can be qualified as an unsuccessful fix for EVA-S on EVA-g.
Example 2 - strikethrough (deletion from the text) of EVA-s.
Example 3 - accidentally touching a pen while writing "s".
However, if we consider the entire sequence of examples 1-4, we can assume that by adding additional elements to the base “s”, artifact -glyphs are obtained. (Which may represent individual phonemes / syllables).
In the first example, “)” is added (which can be equivalent to eva-y with an apostrophe at the top (there are several such examples)), in the second + “|’ ’”, in the third + eva-e, in the fourth + a horizontal line.
In example 5 it is clearly seen that at first the author wrote eva -“c”, then he circled the left foot of the bench (e), wrote the mirror “e” and added an apostrophe.
