rudimentary
Just the essentials
Rudimentary means basic, undeveloped, or at an early stage.
A rudimentary understanding of something covers only the essentials: I have a rudimentary grasp of French.
Rudimentary structures in biology are incompletely developed or vestigial—present but no longer functional: The whale's rudimentary leg bones hint at its land-dwelling ancestors.
