(K.) All of these meanings have been assigned to it in explanations of the saying, أَبِيعُكَ هٰذَا العَبْدَ وَأَبْرَأُ إِلَيْكَ مِنْ خُلْفَتِهِ [I sell to thee this slave, but I am irresponsible to thee for his vice, &c.]: or, according to IAar, the meaning is, خِلَافِهِ [his contrariousness].

Also The last taste of food; (K;) as in the saying, إِنَّهُ لَطَيِّبُ الخُلْفَةِ [Verily it is good, or sweet, in respect of the last taste]; (TA;) and so خَلْفَةٌ: plural خُلَفٌ: and it (خُلْفَةٌ) signifies also loss of appetite for food, in consequence of disease: (so according to the CK:) [or,] according to some copies of the K, خَلْفَةٌ has this latter signification; and so خُلَفٌ: according to other copies, خُلَفٌ is pl of خَلْفَةٌ in this sense: but both these readings require consideration: what is found in the Lexicons is, خَلَفَتْ نَفْسُهُ عَنِ الطَّعَامِ, aorist خَلُفَ , verbal noun خُلُوفٌ; meaning as explained above, in the latter half of the first paragraph.
