For a drama series sitcom...
Isn't the word sitcom short for 'situation comedy'? Is it possible to have a drama sitcom?
Technically you are right, but not 100%.
Derived forms of sitcoms / type of sitcoms are comedy, television program, television show, TV program, TV show, or a humorous
drama based on situations that might arise in day-to-day life.
So technically a show like The Sopranos is considered a sitcom.
And for my two runner ups, I did refer to them as drama series. Not sitcoms.
