Hi,
I am a little bit confused about whether or not I should put 'of' in expressions of measurement and quantity.
In Michael Swan's book ''Practical English Usage'' (p. 226), it is said that ''Of is not used in expressions of measurement and quantity.''
However, in the book ''The American Heritage Guide to Contemporary Usage and Style'' (p. 213), it is said that ''The phrases a half, half of, and half a or half an are all correct, though they may differ slightly in meaning. For example, a half day is used when day has the special sense "a working day," and the phrase then means "four hours." Half of a day and half a day are not restricted in this way and can mean either four or twelve hours.''
Could you please help me with that?
Thanks.
