Yes it’s time for a new wacky word!
Thanks to the very verbose Rants for the word:
: always or often doing something specified
: always or often happening or existing
1 firmly established by long persistence <the inveterate tendency to overlook the obvious>
2 confirmed in a habit : habitual <an inveterate liar>
1 marked by long duration or frequent recurrence <inveterate bursitis>
2 confirmed in a habit : habitual 2 <an inveterate smoker>
Origin of INVETERATE
Middle English, from Latin inveteratus, from past participle of inveterare to age (v.t.), from in- + veter-, vetus old — more at wether
First Known Use: 14th century
Thanks again to Rants for the awesome word!
