الفَكُّ

, according to Er-Rághib, primarily signifies التَّفْرِيجُ [i. e. The opening a thing; and particularly by diduction, or so as to form an intervening space, or a gap, or breach]. (TA.) You say, فَكَّ, first pers. فَكَكْتُ, (S, O, Msb, K,) aorist فَكُ3َ , verbal noun فَكٌّ, (O, Msb,) He separated (S, O, Msb, K) a thing (S, O, K) from another thing; and any two things knit together, or intricately intermixed: (S, O:) or فَكَكْتُهُ I separated one part of it from another part thereof: (Msb:) and ↓ تَفْكِيكٌ likewise signifies the separating two things knit together, or intricately intermixed. (Lth, S, TA.) And He broke [or broke open] a seal, i. e. a sealed piece of clay or wax; (Mgh, Msb, * TA;) in relation to which ↓ يَفْتَكُّهُ occurs as meaning يَفُكُّهُ, though we have not heard it [as a classical expression in this sense]. (Mgh.)

And فَكَّ العَظْمَ, (Mgh, Msb,) aorist and verbal noun as above, (Msb,) He dislocated the bone; put it out of joint. (Mgh, Msb.) [This, or the like, is what is meant by its being said that] الفَكُّ in the hand, or arm, is [i. e. denotes] less than الكَسْرُ. (K.)

And فَكَّ يَدَهُ, (K, TA,) aorist and verbal noun as above, (TA,) He opened, or unclosed, his hand from what was in it: (K, TA:) so in the M. (TA.)

And فَكَكْتُ signifies also I loosed, set loose or free, or let go, anything. (Msb.)

And فَكَّ الرَّقَبَةَ, (S, O, Msb, K,) aorist فَكُ3َ , verbal noun فَكٌّ, (TA,) [lit. He loosed the neck,] means (tropical:) he emancipated [the slave]. (S, O, Msb, K, TA.) فَكُّ الرَّقَبَةِ is explained in a tradition as meaning (assumed tropical:) The assisting in paying the price [of the slave when one is unable to pay the whole of the price]. (O, TA.) In the Qur'an, 90:13, فَكُّ رَقَبَةٍ is said by some to mean (assumed tropical:) The emancipating of a slave: and by some. (assumed tropical:) the man's emancipating himself from subjection to God's punishment by the confession of the unity of God and by righteous doing and then by teaching the same to others. (TA,) فُكَّ فُلَانٌ means (assumed tropical:) Such a one was set free, and at rest, from a thing. (IAar, Th, TA.)

(AZ, S, O, K.) [Or فَكَّ thus used may be from الفَكُّ signifying “ the jaw: ” and so what next follows.]

فَكَكْتُ الصَّبِىَّ I put medicine into the mouth of the boy or young male child [opening his jaws for that purpose]. (S, O.)
