Definition of 'de-accession'

- deaccession \deaccession\, de-accession \de-accession\v. t. [de- + accession. Ca. 1970.] to sell (artwork); -- used of sales of art by museums.
- Note: The word appears to have been coined as a euphemism to avoid the negative connotations of the word "sell", particularly for works donated by benefactors. The practise is justified as a means of acquiring funds for purchase of more valuable artworks. [WordNet 1.5 +PJC]
