Maneno (alfaazh) yametolewa ndani ya lugha ili kuonyesha maana. Neno moja (lafzh) linaweza kuonyesha maana moja tu, kama vile 'Baghdaad', ambalo linaonyesha maana ya mji unaojulikana kwa jina hilo. Neno pia linaweza kuonyesha maana nyingi, kama vile 'Ain', ambalo linaonyesha maana ya 'Ain' ya maji (chemchemi), 'Ain' inayoona (jicho), na jasusi, pamoja na maana nyinginezo. Neno linaweza pia kuonyesha maana mbili au zaidi, kama vile neno 'Ar-Rijaal' (wanaume), kwani linaonyesha kila mtu ambaye ndani yake sifa ya 'Ar-Rajul' (mwanaume) imetimia, na linaweza pia kuonyesha maana iliyokusudiwa (madlool) ambayo imeenea ndani ya aina yake (jins), kama vile: 'Rajul' (mwanaume).

A Lafzh can also indicate many meanings like: ‘Ain’ (eye) which is indicative of the meaning of the ‘Ain of water (spring), the ‘Ain that sees (eye) and the spy amongst other meanings.
