Origin of delve

First recorded before 900; Middle English delven, Old English delfan; cognate with Dutch delven, Old High German telban

Explanation

The verb delve means to dig into, loosen, or investigate. She delved into her family's history and discovered an inventor, a checkers champion, and a circus equestrian in her ancestry. Delve has a literal meaning of to dig into the earth ("to delve the soil," as in preparing a garden, for example), but this sense is rare now. The verb is most often used in the more figurative sense — like to delve into a problem or into someone's personal life.
