Can i say this without the 'to'?
To me that makes more sense too. As ' to' is neuter and here it’s the subject, I suppose.
Both make good sense. It is the "to je/je to" construction for all genders.
"Ona byla dobrá žena" is ok ?
But not "To byla.."?
Perhaps at some women competition where a commitee decides if the women are good women or not... It is strange, not accepted at the moment.
