غمص

غُمَيْصَاآءُ ذ dim. of غَمْصَاآءُ [fem. of أَغْمَصُ]. (TA.) Hence, (TA,) الغُمَيْصَاآءُ [ The star Procyon; ] one of the شِعْرَيَانِ, (S, K,) whereof the other is الشِّعْرَى العَبُورُ [i. e. Sirius]: (TA:) the former is also called ↓ الغَمُوصُ, (S, K,) and الرُّمَيْصَاآءُ, (TA,) and الشِّعْرَى الشَّامِيَّةُ: (IAth:) it is one of the Mansions of the Moon [ accord. to those who make the term نَوْءٌ to signify the auroral setting; namely, the Seventh ]; (TA;) and is in the ذِرَاع; (S;) i. e., it is the greater of the two stars called الذِّرَاعُ المَقْبُوضَةُ: (IAth:) it is called الغميصاء because of its smallness and its littleness of light [in comparison with the other شعرى], from غَمَصُ العَيْنِ: (TA:) [or the reason of its being so called is this:] the Arabs assert that the شِعْرَيَانِ are the sisters of سُهَيْل [or Canopus]; (IDrd, S;) and that they [three] were together; but that سهيل descended into the south, and الشِّعْرَى اليَمَانِيَّةُ [which is Sirius] followed it; (IDrd;) this latter, they say, crossed the Milky way, and was therefore named العَبُورُ; and الغميصاء remained in her place, weeping for the loss of the two others until her eye became affected with غَمَص: (IDrd, K: *) they also assert that thou seest العبور when she rises as though she desired to cross [the Milky Way] (كَأَنَّهَا تَسْتَعْبِرُ); but الغميصاء thou seest not [as yet in any part of Arabia], she having wept until she has become affected with غَمَص.
