>>12375236>>12375243These two images are identical except for the rainbow, but the word order is different. One is "jashin sing yurine music" and the other is "jashin yurine sing rainbow."
This minimal difference actually suggests a lot about the syntax of jashinposter filenames. Observe the following examples:
>>12375233"atre frilly dress idol sing"
Atre is present in the image. "frilly dress idol" are all attributes of Atre. They modify her and therefore follow immediately after her.
>>12375259"atre sing fabulous beckon expectant"
She is singing fabulously while beckoning in an expectant way. The chains of modifiers follow after the head, "sing."
Note that long adverbial strings usually occur either at the very beginning or the very end of a filename, and that the filenames virtually always begin with a noun, typically the subject.
Now we return to the first two images. My hypothesis is that the constructions differ because "sing rainbow" is an adverbial phrase, and thus should move to the end of the filename (because it is not a noun phrase and would not normally occupy the initial position, and because it is the lone adverbial phrase in the filename and thus would not normally go in the middle). The other filename does not contain any adverbial compounds or constructions, and all of its words have equal weight aside from the subject, "jashin."
