فُمَّ

a dialect var. of the conjunction تُمَّ [q. v.]: (K:) or the ف in the former is a substitute for the ث in the latter: one says, رَأَيْتُ عَمْرًا فُمَّ زَيْدًا and ثُمَّ زَيْدًا, both meaning the same [i. e. I saw 'Amr: then Zeyd]: (TA:) and in like manner one says فُمَّتَ and فُمَّتْ, meaning تُمَّتَ and تُمَّتْ. (M and TA voce ثُمَّ.)
