Dictionaries are a pet peeve for me the way they blow in the trend wind, changing definitions at whim while "schools of learning" put out their annual lists of words that are no longer acceptable or cool.
They don't even understand that a dictionary is for words, not phrases. As has already been pointed out, words often have multiple meanings. Put a couple words together into a phrase and the number of possible definitions goes up exponentially.
This is all telling people what to think rather than encouraging them to think for themselves.
Language is (and should be) like art, in a free society, in the creativity of the composer and interpretation of the beholder.
