فَلْتَةٌ ذ A sudden, or an unexpected, event; or a thing that comes upon one suddenly, or at unawares: and anything done without consideration: (IAth, L, TA:) and an affair, or event, that happens without its being soundly, thoroughly, or well, performed or effected: pl. فَلَتَاتٌ: it has no broken pl.: (M, TA:) and فَلَتَاتٌ signifies slips, or faults, of an assembly, or a company of men sitting together. (T, O, K, TA.) One says, مَاتَ فَلْتَةٌ [ He died suddenly ]. (M.) And كَانَ ذٰلِكَ فَلْتَةً That (meaning an affair, or event, S, O) was sudden, or unexpected; (S, M, O, Msb, K, TA;) without premeditation, (S, O, Msb, K, TA,) and without a wavering in opinion: (S, O, K, TA:) or, as some say, it was [ like ] a thing hastily and forcibly seized, or snatched: (L, TA:) and, accord. to some, it is derived from فَلْتَةٌ in the sense next following. (O, * TA.) ― -b2- The last night of any of the sacred months, of which night people differ as to whether it be lawful to war therein or not, wherefore the avenger of blood hastens to obtain retaliation. (O, TA:) or the last night of the month; (S, M, O, K, TA;) i. e., of any month: (S, O, K, TA:) or the last day of a month after which is a sacred month; (S, M, O, K, TA;) as the last of Jumáda-l-Ákhireh; because a man might see therein him on whom he would take his blood-revenge, and if he delayed to do so, and the next day arrived, the sacred month commenced, and the opportunity escaped him: (M, TA:) or an hour observed by the Arabs in the Time of Ignorance; namely, the last hour of the last day of Jumáda-l-Ákhireh: they made hostile attacks, or incursions, during this hour, even when the new moon of Rejeb had risen: Rejeb not commencing until sunset: (AHeyth, T, TA:) or لَيْلَةُ فَلْتَةٍ (or accord. to MF لَيْلَةُ الفَلْتَةِ, TA,) the night by [ the deducting of ] which the month becomes deficient, and by [ the addition of ] which it becomes complete; for sometimes some persons see the new moon when others do not see it, and these latter make a hostile attack, or incursion, upon the others; and it is thus called because it is like a thing that has been let loose after having been bound.
