Spontaneousness comes from spontaneous + -ness; spontaneous derives from Late Latin spontaneus, from Latin sponte ('of one's own accord, voluntarily'). The historical chain includes Latin spontaneus and Latin sponte. The quoted older sense, "of one," supplies the immediate semantic anchor for spontaneousness. The formation is best read as suffixal and borrowed: the word spontaneousness carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "the quality of acting on impulse without planning or external prompting". Related English forms include spontaneous, spontaneity, and spontaneously. The result is a noun whose etymology preserves both the older form and the later English specialization.
