'abiogenicity' originates from Greek/Neo-Latin elements: the Greek prefix 'a-' meaning 'not' plus 'biogenic' (from Greek 'bios' meaning 'life' and Greek 'genēs' meaning 'born'), combined with the English noun-forming suffix '-ity'.

'abiogenicity' developed in scientific English by adding the suffix '-ity' to 'abiogenic' (itself formed from Greek elements via Neo-Latin/Modern Latin usage, as in 'abiogenesis'), producing the abstract noun 'abiogenicity'.

Initially associated with discussions of 'abiogenesis' (the origin of life without biological precursors), the term evolved as a technical abstract noun to denote the property or state of being produced by nonbiological processes — i.e., 'not of biological origin'.
