فِلَاقٌ

2.
Also The state of milk's becoming thick and sour, so that it curdles, or becomes dissundered: (IAar, K, TA:) [or it may be here a plural of فِلْقٌ (q. v. voce فِلْقَةٌ), for in a verse cited by IAar the milk in this case is termed ذُو فِلَاقٍ, so that it may mean the separate portions of curd of milk that has become thick and sour; though it is said in the TA that its plural is فُلُوقٌ, for this I think very questionable. See also the next preceding paragraph]
