I have picked up a certain word, changed each of its consonants into a letter C and each of its vowels to V.
Then, to cause you extra excitement, introduced an error i.e. changed one of the letters (either replaced C by V or vice versa).
It is
Obvious that the word is not an esoteric one and may be recovered by considering the following hint:
the number 12544 will lead you to the distorted word, you will correct it to get the original one.
Enjoy!
I guess that one of the words is Obvious, based on the fact that it is capitalized. Obvious = VCCVVVC
Looking for another 7 letter word in the problem does not work.
Neither recover nor certain nor changed nor distort is one vowel/consonant different. The best I could come up with was Uncover = VCCVCVC.
Are the words Obvious and Uncover? I do not see the connection to either 12544 or 12100, so I do not know which was the original and which was changed.
