Erring; going astray; deviating from, or losing, or missing, the right way: or becoming lost; perishing; or dying: synonym ضَالٌّ: (K:) and so ↓ خَسِرٌ (TA) and ↓ خَسِيرٌ and ↓ خَيْسَرَى, (K, TA, but the last written in the CK خَيْسَرِىٌّ,) or ↓ خَيْسَرٌ, for it is said to occur [as an epithet] only in the following saying, in which خَيْسَرَى is said to be put for خَيْسَرٌ to assimilate it to preceding words: بِفِيهِ البَرَى وَ حُمَّى خَيْبَرَى وَ شَرٌّ مَا يَرَى فَإِنَّهُ خَيْسَرَى [In his mouth be dust, and may the fever of Kheyber befall him, and evil be that which he shall see, for he is one who goeth astray: but in the TA, in article ورى, is another reading; for بفيه البرى, substituting بِهِ الوَرَى, meaning a certain disease]. (TA.) [Hence,] أَحْمَقُ خَاسِرٌ دَابِرٌ دَامِرٌ [Foolish, or stupid, erring, and utterly perishing]. (T in article بت. [See بَاتٌّ: and see also دَامِرٌ.])
