ربع

رُبَعَ ذ : see رُبَاعُ. -A2- رُبَعٌ A young camel brought forth in the [ season called ] رَبِيع [here meaning autumn ], which is the beginning of the breedingtime: (S, Msb, K:) so called because he widens his stepping, and runs: [see 1, near the end of the paragraph:] (TA:) fem. with ة: pl. masc. رِبَاعٌ [a pl. of mult.] and أَرْبَاعٌ [a pl. of pauc.]; (S, Msb, K;) both irreg.; for accord. to the rule given by Sb, the pl. should be رِبْعَانٌ [like صرْدَانٌ pl. of صَرَدٌ]: (TA:) pl. fem. رُبَعَاتٌ (S, Msb, K, TA [in the CK, erroneously, رَبْعاتٌ]) and رِبَاعٌ. (K.) Hence the saying, مَا لَهُ هُبَعٌ وَلَا رُبَعٌ He has not a young camel brought forth in the end of the breeding-time nor one brought forth in the beginning thereof. (S, TA.) [See another ex. voce بُلَعٌ.] ― -b2- [Hence, also,] الرُّبَعِ (assumed tropical:) A very small star in the midst of the عَوَائِذ, which are in the head of التِّنِّين [or Draco ]. (Kzw.)
