«وَأَجْتَنِي الْيَانِعَ الْجَنِيَّ مِنَ الْقَوْلِ»
I harvest the ripe fruit of speech.
The contrasting half-verse, «وَغَيْرِي لِلْعُودِ يَحْتَطِبُ», pictures others gathering firewood. The comparison elevates his own refined verbal selection above ordinary efforts.
*Ajtanī* is to gather or reap; *yāniʿ* means ripe; *yaḥtaṭib* means to collect firewood. The contrast is a device of literary self-praise, not a neutral judgment on everyone else’s ability.
