«موددة»
An expression relating to affection, used here without the expected assimilation.
The familiar assimilated form is مَوَدَّة (mawaddah). Displaying the two relevant consonants separately where assimilation is expected supplies another example of departure from a morphological rule.
The defect is not restricted to plural formation. It may involve idghām (assimilation) and the internal structure of a word, showing the relation between morphology and rhetoric.
