وَكَأَنَّمَا الْتَفَتَتْ بِجِيدِ جَدَايَةٍ رَشَإٍ مِنَ الْغِزْلَانِ حُرٍّ أَرْثَمِ
When she turned, her graceful neck seemed like that of a young gazelle, delicate and free, with a distinctive pale marking near its mouth.
Kaʾannamā introduces the simile. Jīd is a neck; jadāyah and rashaʾ belong to the vocabulary of young antelope; artham indicates a distinctively marked muzzle. The comparison renders a brief turning movement vivid through an animal familiar to the poem’s audience.
