removal or opening of a cycle/ring
Etymology
'decyclization' originates from Modern English, formed from the prefix 'de-' (from Latin 'de' meaning 'away from, remove') + 'cyclization' (from 'cycle' + suffix '-ization'), where 'cycle' ultimately comes from Greek 'kyklos' meaning 'circle'.
'cycle' comes from Greek 'kyklos' ('circle'), entered Latin/Medieval Latin as 'cyclus' and Middle French/Latin forms, became English 'cycle'; 'cyclization' developed as the noun form meaning 'formation of a cycle' and 'de-' was prefixed in Modern English to indicate removal, yielding 'decyclization'.
Initially the components referred simply to 'circle' (kyklos) and the prefix 'de-' meant removal; combined in Modern English the term now specifically denotes the process of removing or opening a cycle (chemically or structurally).
