Sense: adjective/1
Extended, prolonged, lengthy, and extensive all describe something longer or larger than usual, but they differ in focus. Extended is the most neutral and versatile term, used for time (extended stay), physical space (extended arm), and scope (extended family). Prolonged emphasizes unwanted continuation beyond what is necessary, often carrying a negative tone (prolonged illness, prolonged delay). Lengthy is more informal and applies mainly to time or written works (lengthy speech, lengthy document). Extensive highlights wide coverage or large scope rather than length (extensive damage, extensive collection). For a deadline, use extended, not prolonged — 'the librarian gave him an extended deadline' sounds neutral, while 'prolonged deadline' would wrongly suggest the deadline itself was a problem.

Etymology
Extended comes from the Latin verb extendere, meaning 'to stretch out' — formed from ex- ('out') and tendere ('to stretch'). It entered English in the 15th century, first as a verb and later as an adjective describing something that has been stretched out in space or time.
