DefectUnderlying issue
Ḍaʿf al-TaʾlīfUnaccepted syntactic composition
Tanāfur al-KalimātHarshness across otherwise good words
Taʿqīd LafẓīEntangled construction or order
Taʿqīd MaʿnawīObscure link to the intended meaning
A further condition remains: the constituent words must themselves be faṣīḥ. Appropriate syntax cannot rescue an utterance built from an individually defective word. Sentence-level faṣāḥah adds to, rather than replaces, word-level faṣāḥah.
