Adding -ality to a word mimics terminology in the sciences[1], the sciences have broad authority, thus you cloak your
whatever in that same "science-y" authority.
[1] Why is that? Thank the many centuries of non-vulgate languages in the arts and sciences. Since they come from different noun/consonant/grammar structures, when those loanwords are shoved into another language, they gain a whole pile of prefixes and suffixes to make them fit. Of course, "option" is a longstanding common word in English, so we're adding the "-ality" to make it esoteric, which marks it as a possible "science-y" word. This effect is starting to wear off, but unfortunately it's also taking science down with it.
