lacking hydrogen
Etymology
'hydrogen-free' is formed in English by combining 'hydrogen' (from Greek 'hydro-' meaning 'water' and '-gen' meaning 'producer') with the suffix '-free' (meaning 'without').
The term 'hydrogen-free' was created in modern English by combining the scientific term 'hydrogen' with the common English suffix '-free', following the pattern of other 'X-free' compounds.
Initially, it simply described something without hydrogen, and this meaning has remained unchanged in scientific and technical contexts.
