Is desert related to dessert [closed]

I understand that dessert means something like clearing off (table) and desert and deserted seem sort of related to this. But I have been told this is a complete wrong idea.

Etymonline has a good article on these words.

Dessert comes from middle French in the c. 1600 (in turn derived from Latin) a service of fruits and sweets at the close of a meal," c. 1600, from Middle French dessert (mid-16c.) "last course," literally "removal of what has been served," from desservir "clear the table," literally "un-serve," from des- "remove, undo" (see dis-) + Old French servir "to serve" (see serve (v.)).

Desert is derived from desero (I desert) desertum means something deserted or abandoned.

So, no, the similarity is a 'false friend'. they look alike, but are quite different.
