Core sense — dumb, unable to find words or to replygenerated
1the same as أَخْرَسُ [meaning dumb, either by natural conformation or from inability to find words to express what one would say]—بَكِيمٌ
Or: not having the understanding to reply, nor the ability to frame speech well, though possessing the faculty of speech; whereas اخرس means speechless, or without the faculty of speech, by natural conformation, like the beast that cannot articulate; unable to find words to say what one wants; unable to reply. Or: dumb by natural conformation.
Feminine بَكْمَآءُ; plurals بُكْمٌ and بُكْمَانٌ, both plurals of أَبْكَمُ, just as صُمٌّ and صُمَّانٌ are plurals of أَصَمُّ; and the plural of بَكِيمٌ is أَبْكَامٌ.
In the Qur'ān 2:166, بُكْمٌ means people in the condition of one who has been born dumb; or, as some say, deprived of their intellects; or ignorant and ignoble, because they profit little by the faculty of speech, so that they are as though they had been deprived of it.
The phrase فِتْنَةٌ صَمَّآءُ بَكْمَآءُ عَمْيَآءُ, occurring in a tradition, [literally] meaning [A sedition, or the like,] deaf, dumb, blind, applies to a فتنة that does not withdraw or become removed; or, as some say, to one which, because of the confusion attending it and the perishing of the sound and the sick in it, is likened to the deaf and dumb and blind person who does not pursue the right course to a thing but goes at random like a weak-sighted she-camel.
Qur’ān 2:171 approximate — somewhere between 2:166 and 2:175 Lane cites “Kur ii. 166”
Qur’ān 2:171 the verse Lane’s citation points to, and it uses this root
وَمَثَلُ ٱلَّذِينَ كَفَرُوا۟ كَمَثَلِ ٱلَّذِى يَنْعِقُ بِمَا لَا يَسْمَعُ إِلَّا دُعَآءً وَنِدَآءً ۚ صُمٌّۢ بُكْمٌ عُمْىٌ فَهُمْ لَا يَعْقِلُونَThe parable of those who reject Faith is as if one were to shout Like a goat-herd, to things that listen to nothing but calls and cries: Deaf, dumb, and blind, they are void of wisdom.Abdullah Yusuf Ali, The Holy Qur’ān (1934)
