I noticed mispronouncing of these words for a whopping nine out of ten times. The content (meaning – what is contained, index) which everybody usually pronounce as KANTENT should actually get pronounced as KONTENT. Below is mentioned two totally different words with utterly different meanings….
1) content (kantent) (noun) – ease of mind, satisfied
eg. She was content with her job profile.
2) content (kontent) – (adjective) – what is contained, index
eg. the contents of room, the content of speech
