   ML> as i understand it, just like seeing one deer or many   
   ML> deer, welcome is also the past tense of welcome   
      
   Hardly.  The dictionary gives "welcomed" instead of   
   "welcame, welcome".  It is because in all tenses of   
   "welcome" the "come" part remains the past participal of "to   
   come" with adjectival meaning.  "come" has the same meaning   
   in "I am come with peace."   
      
   ML> but then that may depend on context as i remember a book   
   ML> containing a passage similar to "he was welcomed at the   
   ML> gates of the city"... possibly it has to do with noun vs   
   ML> verb vs adjective usage?   
      
   No.  When used as a verb, its past tense and past participle   
   are always "welcomed".
