The word "shininesses" is a derivative form of the adjective "shiny", which describes something that has a bright or lustrous appearance. The etymology of "shiny" can be traced back to the Middle English word "shinen", which meant "to shine" or "to gleam". This Middle English term evolved from the Old English word "scīnan" or "sċeon", which also meant "to shine". Ultimately, these Old English roots are related to the Proto-Germanic word "skīnanan", which had the same meaning. So, "shininesses" is formed by adding the suffix "-ness" to "shiny", thus referring to the quality or state of being shiny.
