ل ف ظl-f-ẓ
(ض) لَفَظَ يَلْفِظُ لَفْظًاlafaẓa yalfiẓu lafẓan: to cast out of the mouth, to spit out; from this comes lafẓ in the sense of a spoken word, since the tongue casts it out. Only once in the Quran: ﴿مَا يَلْفِظُ مِنْ قَوْلٍ إِلَّا لَدَيْهِ رَقِيْبٌ عَتِيْدٌ﴾ (Qāf 50:18) — i.e. he utters not a word but a watcher is ready.
Form V (tafaʿʿul) تَلَفَّظَ يَتَلَفَّظُ تَلَفُّظًاtalaffaẓa yatalaffaẓu talaffuẓan: to utter a word or statement; to pronounce; to speak (this verb is not used in the Quran).
