to receive the rights of a negotiable instrument without the obligation of the seller who formed the contract.
一般用在法律合同或條文里面,意思是不用承受法律責(zé)任而承受義務(wù)或者物質(zhì).
比如：
such a buyer takes free of a perfected security interest in the inventory,even if he knows of the security interest,unless he knows that the sale is in violation of the security agreement.
這樣的買家可以免除貨物的保證義務(wù),即使他知道他所購買的貨物本身是被抵押物.
