Is disaccharide consider as a simple sugar?

Honey is a mixture of many compounds, some of which are disaccharides.

A di-saccharide is a carbohydrate formed by two mono-saccharides. Sucrose, common table sugar, is a typical example of a disaccharide.

Honey gets the majority of its flavor from the monosaccharides fructose and glucose (approximately 70% of honey is fructose and glucose), and contains the disaccharide sucrose (~1%) - which is made from the combination of fructose and glucose.
