مُفْتَعَلٌ

A writing forged, or falsified. (Mgh.)

And Poetry composed with originality, not in imitation of any model. (TA.)

جَاءَ بِالْمُفْتَعَلِ, meaning It produced a grievous, or distressing, effect, (K, TA,) is a phrase mentioned by IAar, as used by Ed-Dubeyree when asked respecting a wound that he had received and that rendered him sleepless, and as used by him in respect of anything [unprecedented]: thus one says, عَذَّبَنِى وَجَعٌ أَسْهَرَنِى فَجَاءَ بِالْمُفْتَعَلِ i. e. [A malady that rendered me sleepless, tormented me,] and produced pain that had not been known before. (TA.)
