«ويسمى تعقيدًا لفظيًا»
This is called verbal complexity.
When excessive fronting, postponement, or separation pulls related words apart and forces the reader to reconstruct the sentence in order to discover the intended sense, the expression suffers from verbal taʿqīd.
Long sentences are not necessarily defective. The problem is that the relationships among syntactic elements become hidden despite the use of familiar words.
