وَلَا يَجْتَمِعُ مَعَ وَزْنِ الْفِعْلِ أَصْلًا، وَيَجْتَمِعُ مَعَ الْعَلَمِيَّةِ، كَعُمَرَ وَزُفَرَ، وَمَعَ الْوَصْفِ، كَثُلَاثَ وَمَثْلَثَ وَأُخَرَ وَجُمَعَ.
Translation: ʿAdl does not combine with a verb pattern; it does combine with proper-name status, as in ʿUmar and Zufar, and with adjectival status, as in thulāth, mathlath, ukhar and jumaʿ.
To “combine” here means that two effective causes of preventing full declension occur in one word; it does not mean a plural form.
