pron: covert has historically been pronounced (ˈkʌv ərt) with stressed (u), the vowel heard in cover, mother, some, and many other similarly spelled English words. As an adjective, however, covert, by analogy with overt (oʊˈvɜrt, ˈoʊ vərt) its semantic opposite, has developed the pronunciation (ˈkoʊ vərt) and this is the more common pronunciation in American English. For the noun, (ˈkʌv ərt) remains the more frequent pronunciation.
