rehumidifying
|re-hu-mid-i-fy-ing|
/riːˈhjuːmɪdɪfaɪ/
(rehumidify)
make moist again
Etymology
'rehumidify' originates from the Latin-derived prefix 're-' (from Latin 're-') meaning 'again' combined with 'humidify', which ultimately comes from Latin 'humidus' meaning 'moist' and the verb-forming element '-ify' (from Latin '-ificare').
'humidify' developed from Latin 'humidus' → Late Latin/Medieval Latin forms (e.g. 'humidificare') → Old French/Modern French 'humidifier' → English 'humidify'. The modern English verb 'rehumidify' was formed by adding the prefix 're-' to 'humidify'.
Initially the roots meant 'again' and 'moist', and over time the combined modern meaning became 'to make moist again' or 'to restore moisture'.
