Hi, Anton Shepelev!   
   I read your message from 26.01.2017 18:55   
      
    AK>> They don't think of a Gerund if there is a noun   
    AK>> expressing the similar meaning.  So "invade" requires   
    AK>> nothing.   
      
    AS> Who are "they"?  Can you provide arguments instead of the   
    AS> appeal to authority?   
      
   When you hear "they say" don't ask who. ;) It is like an idiom.   
      
    AK>> You require a spell checker however. ;)   
    AS> I know, but am trying to make do without.   
      
    AS>>> I therefore view "invasion" in the phrase "invasion of   
    AS>>> Iraq" as a gerund.   
      
    AK>> What about seeing it as a noun? :)   
      
    AS> Then would you please mark for me the difference between   
    AS> "the invasion of Iraq" and "the invading of Iraq"?   
      
   I looked in my textbook: there is no Gerund in "the invading of Iraq"   
      
   1. Gerund is not used with articles   
   2. Gerund is used without preposition.   
   2. Gerund can't be used with adjectives (but we can easily add an adjective   
   here "the outrageous invading of Iraq"   
      
   In short we have here an "ing noun". But since we have "invasion", I doubt   
   that using "invading" as a noun is OK.   
      
   Many verbs don't have ing nouns. For instance, produce(production, not   
   producing), manufacture(manufacture, not manufacturing) sell(sale, not   
   selling)".   
      
   Bye, Anton!
