Word origin
[1850–55; post- + glacial]This word is first recorded in the period 1850–55. Other words that entered Englishat around the same time include: boneyard, ethos, ethylene, heavyweight, overprintpost- is a prefix, meaning “behind,” “after,” “later,” “subsequent to,” “posterior to,”occurring originally in loanwords from Latin (postscript), but now used freely in the formation of compound words (post-Elizabethan; postfix; postgraduate; postorbital)
