مَرَّةٌ

A time; one time; [in the sense of the French fois;] synonym تَارَةٌ: (Msb:) one action; a single action or act; (M, K;) as also ↓ مَرٌّ: (M, K: [but see what follows:]) [a bout; an instance; a case; and a single temporary offection or attack; a fit; as, for instance, of hunger, thirst, disease, and the like:] plural مَرَّاتٌ (A, Msb) and مِرَارٌ (S, M, A, Msb, K) and مِرَرٌ and ↓ مَرٌّ [or rather this is a coll. gen. n. of which مَرَّةٌ is the n. un.] and مُرُورٌ; (M, K;) the last on the authority of Aboo-'Alee, and occurring in the following verse of Aboo-Dhu-eyb:

تَنَكَّرْتَ بَعْدِى أَمْ أَصَابَكَ حَادِثٌ

مِنْ الدَّهْرِ أَمْ مَرَّتْ عَلَيْكَ مُرُورُ

[Hast thou become altered since I saw thee, or hath an accident of fortune befallen thee, or have vicissitudes come upon thee?] but Es-Sukkaree holds that مرور is a verbal noun; and IJ says, I do not think this improbable, and that the verb is made feminine because the verbal noun implies muchness and genus. (M.) You say فَعَلْتُهُ مَرَّةً [I did it once], (A, Msb,) and مَرَّاتٍ and مِرَارًا [several times]. (A.) [And بِالْمَرَّةِ At once.] And لَقِيَهُ ذَاتَ مَرَّةٍ [He met him once]: only used adverbially: (M, K:) so says Sb. (M.) And لَقِيَهُ ذَاتَ المِرَارِ He met him many times: (M, K:) [or this has a different signification; for] you say فُلَانٌ يَصْنَعُ ذٰلِكَ الأَمْرَ ذَاتَ المِرَارِ meaning Such a one does that thing sometimes, and sometimes he leaves it undone. (ISk, S.) Also, جِيءْتُهُ مَرًّا أَوْ مَرَّيْنِ, i. e., مَرَّةً أَوْ مَرَّتَيْنِ [I came to him once or twice]. (M, K.)
