anti-diuretic
|an-ti-di-u-ret-ic|
/ˌæn.ti.daɪ.əˈrɛt.ɪk/
prevents or reduces urine production
Etymology
'anti-diuretic' is formed from the prefix 'anti-' (from Greek, meaning 'against') combined with 'diuretic' (from New Latin/Greek 'diureticus'/'diourein', relating to urination).
'diuretic' comes from New Latin 'diureticus' and Greek 'diourein' meaning 'to urinate'; English then formed 'diuretic' and later the compound 'anti-diuretic' by adding the prefix 'anti-'.
Originally formed to mean 'against increased urination', it has come to be used specifically for agents or properties that reduce urine production ('preventing or reducing urine output').
