Background: (Note: Sorry if this is a repeated question. I'm not sure if I should ask this question in the Arabic forum or Urdu forum (Indo-Iranian Languages)...so am posting in both to see what the different replies might be!) IIL forum post here! خبرناک / Khabarnaak, an Urdu program on a Pakistani TV channel has a segment زبان و بیان (zabaan = lisaan لسان) zabaan-o-bayaan, in which the host discusses various غلط العام ghalat-ul-a'am , wrong pronunciations and usages of words, phrases, and grammar. In a recent episode, it was said that عربی الفاظ مشتمل on four حروف with a شد/تشدید on the second حرف .... represent an element of repetition. Examples given: حَمّام : a place to get hot water over and over/again and again قوّال : a person who recites/sings اقوال over and over/again and again Question: Is this "rule" correct? Could members provide a few more examples of such words? (Browsing the Online Urdu dictionary for Arabic derived four letter words with a tashdeed on the second letter, the rule seemed to make sense in many cases like صِدِّیق but not for some like شَوّال ...which could be due to my lack of knowledge!) Thanks!
