(degas)
remove gas
Etymology
'degassing' originates from the prefix 'de-' (from Latin 'de-' meaning 'remove' or 'reverse') combined with 'gas' (from Dutch/Modern Latin 'gas'), where 'de-' indicates removal and 'gas' refers to gaseous substance.
'degassing' derived from the verb 'degas' (English formation using the prefix 'de-' + 'gas'); 'gas' itself was borrowed into English in the mid-17th century from Dutch 'gas' (a word popularized by Jan Baptista van Helmont), and the verb 'degas' and its noun/gerund forms developed later in technical contexts.
Initially it carried the literal sense 'remove gas from X'; over time the term has remained close to this technical meaning but broadened into specialized fields (chemistry, metallurgy, volcanology) with context-specific methods and implications.
