Whenever I've had this problem interpreting between senses in a dictionary
I have usually found that the dictionary's text was at fault, not the
intended disjointness. I usually can resolve such problems by consulting
an unabridged dictionary in which there is sufficient space to make the
distinctions left out of the abridged versions--and where the indispensible
example sentences are given. In the absence of these details, as for
example would appear in a Pocket Dictionary, there is sometimes barely a sign
of the intended distinction.
