situated directly below (something else)

our bedroom is right underneath theirs

four names written underneath each other

so as to be concealed by (something else)

money changed hands underneath the table

underneath his aloof air, Nicky was a warm and open young man

situated directly below something else

there was plenty of storage room underneath

a crane lifted slabs of concrete to rescue people trapped underneath

so as to be concealed by something else

paint was peeling off in flakes to reveal greyish plaster underneath

she seemed to have no emotions, but in fact she was very sensitive underneath

the part or side of something facing towards the ground; the underside

a wart on the underneath of his foot
