The word "succumb" is commonly misspelled as "succum" due to the tricky silent "b" at the end. The correct pronunciation is /səˈkʌm/ or "suh-KUM." The "u" in the middle is pronounced like the "uh" sound in "butter." The spelling of this word comes from its Latin origins, where it was spelled as "succumbere" which means "to yield" or "to give in." So, next time you're tempted to omit the "b" in "succumb," just remember its Latin roots.
