The Oxford Thesaurus An A-Z Dictionary of Synonyms INTRO ...

literal uses and figures of speech, between transitive and
intransitive verbs, and between synonyms that differ in more subtle
aspectual characteristics of meaning or syntax. (See also 7, below.)
Not all senses of all words are covered for either or both of the
following reasons: the sense, though it exists, is relatively rare in
ordinary discourse and writing; there are no reasonable synonyms for
it. Thus, this sense of mercy,
an affecting or moving of the mind in any way; a mental state
brought about by any influence; an emotion or feeling: Mercy
is an affection of the mind.
is not covered for the first reason, as it is a literary and somewhat
archaic usage. The same can be said for the sense,
a bodily state due to any influence
and for other senses listed in the largest dictionaries but rarely
encountered except in literary contexts. Even in such contexts it
would be unusual to need a synonym for this word and others like it.
4. Cross references
There are very few cross references between main listings in the
Thesaurus. Where such cross references do occur, they are simple and
straightforward:
superior adj....3 See supercilious, above. --n 4 See
supervisor, below.
A number of cross references occur within entries, between variant
forms of an expression. At the entry for take, for example, as one can
say either take or take it in the sense of 'understand' etc., the
option is shown in the following way:
take v...19 understand, gather, interpret, perceive,
apprehend, deduce, conclude, infer, judge, deem, assume,
suppose, imagine, see: I take him to be a fool. I take it from
your expression that you've had bad news.
33 take it: a withstand or tolerate or survive punishment or
abuse, survive: The Marines are extremely tough and can take
