Hence, (Msb, K,*) or from التَّرْخِيمُ signifying, as some say, The cutting off [a thing], or cutting [it] at its extremity, or curtailing [it], (S,) the تَرْخِيم of the name, (S, Msb, K,) in the vocative form of speech; (S;) [according to general opinion,] because it facilitates the pronunciation thereof; (K;) i. e. the [abbreviating by the] eliding of the end thereof, for the alleviation of the utterance; (Msb;) the curtailing a name of its last letter, or more; (S, TA;) as when, to one whose name is حَارِثٌ or مَالِكٌ, you say يَا حَارِ or يَامَالِ: but according to Z, in the A, it is from the ترخيم of the hen; because this is only on the occasion of the cutting short (قَطْع) [of the laying] of the eggs: (TA:) [in like manner also] the تَرْخِيم of the diminutive is the [abbreviating thereof by the] cutting off of [one or more of] the augmentative letters [and sometimes of radical letters]; as when, in forming the diminutive of أَسْوَدُ [and that of إِبْرَاهِيمُ], one says سُوَيْدٌ [and بُرَيْهُ].
