I counted 6, but I'm sure I'm not a genius. It may very well be that I don't have a "human brain"!! hehehe.
I'll explain: The "human brain" that tends to consider the "f" in "of" as a "v" is surely the human brain of a native speaker of English -or any other languages in which that consonant can be pronounced "v". I'm a native speaker of Spanish, and in my mother tongue the letter "f" sounds /f/; that is probably why I did not miss any of them.
This test does not show how intelligent or dumb I am, but it surely reminds me that, no matter how good my English may be, I did not simply "acquire" it easily but I "learned" it, meaning I had to study hard! In my Spanish-speaker brain, it seems an F is still an F.
Interesting, huh?
Elena (and any other speakers of ESL or EFL) what do you think? Do you agree with me?
