“Fa-ẓallat aʿnāquhum lahā khāḍiʿīn”
“Then their necks would remain bowed before it.” (al-Shuʿarāʾ 26:4, excerpt)
“Aʿnāq” refers to necks, yet “khāḍiʿīn” appears in a masculine rational plural form. The relation becomes clearer when the necks are taken as representing their owners: their physical bowing signifies the people’s submission.
A purely mechanical description of the neck as an anatomical part misses the figure. The visible part of the body stands for the people who submit, while the grammatical form directs attention to that human referent.
Grammatical agreement can thus disclose the intended sense instead of merely presenting a technical puzzle.
