Hello dear friends, If I were depressed, could I say I'm having melancholy. or I'm having melancholia.? Actually what I want to know is, are melancholy and melancholia synonyms? Do they mean the same? Thanks! Oh, I just found out that "melancholy" is a depression that only applies to the mental symptoms of depression, whereas "melancholia" can be physical and mental. To conclude, "melancholia" means depression, and "melancholy" means a sad thoughtful state of mind. Can somebody confirm me this please?
