Abstract
The world of construction is filled with contronyms-words having two completely opposite meanings. Has a building weathered many seasons, or is it falling apart because it is so weathered? Is the contractor providing good oversight, or did an oversight set off an angry client? Anyone in the construction industry can vouch that almost nothing is ever quite as straightforward as one might hope.
