Understudied → It is formed from "under-" (meaning beneath or less than) and "studied" (from the verb "study", which comes from Latin "studere", meaning to apply oneself to learning). The word "understudied" refers to something that has received less attention or study than it deserves.
Think of something that is 'beneath' ('under-') the level of attention it should have received in terms of 'study' — that's why understudied means not studied enough.
