Etymology
'non-photochemical' originates from the prefix 'non-' meaning 'not' and 'photochemical' which is derived from 'photo-' meaning 'light' and 'chemical' meaning 'relating to chemistry'.
'Photochemical' evolved from the Greek word 'phōs' meaning 'light' and 'chemical' from the Latin 'chimicus'. The prefix 'non-' was added to indicate the absence of light-related chemical reactions.
Initially, 'photochemical' referred to chemical reactions caused by light. The addition of 'non-' specifies the absence of such reactions.
