مُفْتَتَحٌ

is a verbal noun [signifying The act of opening and commencing &c.]: and a n. of place and of time [signifying a place of opening and commencing &c. and a time thereof: and also the opening portion of the Qur'an; as shown voce خَاتَمٌ, q. v.]: and is a commonly-known and chaste word: though it has been said that مُخْتَتَمٌ [which has the contr. significations] is not a chaste word: (TA in the present article:) this, however, is not correct; for it is a chaste word, and of frequent occurrence. (TA in article ختم.)
