Word origins (as a writer you should be aware of this sort of thing)

 Intrepid comes from the Latin word intrepidus, itself formed by the combination of the prefix in-, meaning “not,” and the adjective trepidus, meaning “alarmed.”

 

Umbriferous (uhm-BRIF-uh-ruhs)  Casting a shadow. From Latin umbra (shade, shadow) + ferre (to bear). Some related words are umbrella, adumbrate, and somber.
