Lu,
Unfortunately you do not read it correctly, O man of many books!
The Concise Oxford Dictionary states that hover is pronounced 'hover'.
That is 'ho' as on HOt, 'v' as in 'V' (not vee, obviously) and 'er' as in hER.
Incidentally, we tend to use 'spelt' as the past tense of spell.
What is this Websters College Dictionary thing. It is not
American, I hope. How can you have an American dictionary of the
English language? (J for joke).
You say tohmaytoe, I say.........
