اجتدث He made, or prepared, a جَدَث, i. e., a grave, or sepulchre; or did so for himself. (Ṣ, Ḳ, TA.)

جَدَثٌ A grave; a sepulchre; pl. أَجْدَاثٌ (Ṣ, Mṣb, Ḳ) and أَجْدُثٌ; (Ṣ, Ḳ;) of which latter, J cites an ex., but in this instance it is the proper name of a place. (TA.) It is of the dial. of Tihámeh: the people of Nejd say جَدَفٌ: (Mṣb:) or [as some say] the ف in the latter is a substitute for the ث in the former; for اجداث is used as a pl. by common consent, and اجداف is not used: (TA:) but Suh affirms, in the R, that the latter pl. is used by Ru-beh. (TA in art. جدف.)
