noun peh-NOOM-brah Rare

Origin: From Latin paene ('almost') + umbra ('shadow'), entering Spanish via scientific Latin.

Also means

penumbra

Usage Note

Penumbra in everyday Spanish means a dimly lit or shadowy zone, not just the astronomical partial shadow. It often appears in literary prose to evoke mystery or ambiguity. In astronomy it retains the technical meaning of the outer shadow of an eclipse, distinguishable from umbra (full shadow).

Examples

"La habitación estaba en penumbra."

The room was in semi-darkness.
