thin covering layer (of paint, varnish, etcetera)
Civilization is only a veneer that covers the true barbarity beneath.
: when VE (we) travel in train, VE (we) get railNEER, which has a thin covering outside to decorate veneer:ven (when)+eer (beer). so my mother caught me and asked me when did u drink beer as i could not COVER it before her. veneer sounds like elaneer (tender coconut). and inside elaneer there ll be a thin layer of white edible coconut. so veneer = thin layer
