Opposites
Many synonym sets are followed by one or more words that have the opposite
meaning from the headword, often called 'antonyms'. There are several different
kinds of antonym. 
Tr u e
 and 
false
 are absolute antonyms, with no middle ground.
Logically, a statement is either true or false, but cannot be slightly true or rather
false. 
Hot
 and 
cold
, on the other hand, are antonyms with gradations of meaning: it
makes perfectly good sense to say that something is rather hot or very cold, and
there are a number of words (
warm
, 
tepid
, 
cool
) which represent intermediate
stages. It makes sense to ask about something "How hot is it?" but that commits
the speaker to the notion that it is hot at least to some extent. So 
hot
 and 
cold
 are
at opposite ends of a continuum, rather than being absolutes.
For many words, there is no single word that counts as an antonym, but there may
be a phrase that gets the opposite meaning across. For example, what is the
opposite of 
senile
? There is no exact antonym, but the phrase 
in the prime of life
gets the opposite meaning across. In this title the broadest possible definition has
been adopted, giving the maximum amount of information to the user. In some
cases, a phrasal antonym is given for a phrasal subentry, e.g. 
bottle things up
 as an
antonym for 
let off steam
.
The antonyms given in this thesaurus are not the only possible opposites, but they
are usually the furthest in meaning from the headword. By looking up the 'opposite'
word as an entry in its own right, the user will generally find a much larger range of
antonyms to choose from. For example, at the entry for 
delete
 the user will find:
-OPPOSITE(S) add, insert.
Both 
add
 and 
insert 
are entries in their own right.
Related terms
A special feature of 
NOTE
 is that it gives not only synonyms and opposites but also
other related terms, especially for concrete nouns such as 
milk
 (where 
lactic
 is not
a synonym, but a word with a related meaning) and 
town
 (
municipal
, 
urban
, and
oppidan
). There are two types of related words: the first are adjectives which
usually mean 'relating to' the headword but have a different origin (e.g. 
lactic
 for
milk
) and which may therefore not spring to mind as quickly as a straightforward
derivative such as 
milky
. The second type is typically a word very closely associated
with the headword, but with a different meaning. For example, a related word may
denote a part of the thing denoted by the headword, or it may denote a particular
form of this thing. Thus, at 
barrel
, the related words given are 
cooper
, 
stave
, and
hoop
 - a maker of barrels, and two important components of a barrel.
Combining forms
Combining forms are given after related terms. These are very similar to the first
kind of related terms, but in the form of a prefix or suffix that is used in combination
with other elements, e.g. 
oeno
- with the sense 'wine', as in 
oenology
, or 
-vorous
with the sense 'eat', as in 
carnivorous
.
Awkward synonyms and confusables ( )
One thing a plain list of synonyms cannot do is help the user choose between them
by describing their nuances and connotations. For instance, the words 
blunt
,
candid
, 
forthright
, 
frank
, and 
outspoken
 are all given as synonyms of each other,
because they all have roughly the same meaning. But there are subtle differences.
This set comprises one of the 120 studies of 'Awkward Synonyms' in the 
New
Oxford Thesaurus of English
, devoted to explaining the differences in meaning
between close synonyms. The distinctions are based on careful analysis of actual
usage as recorded in the British National Corpus, and examples of typical usage
are given, selected from the British National Corpus and the citation collection of
the Oxford Reading Programme.
The other type of article displayed as a note ( ), 'Confusables', compares
words which may cause difficulty for the opposite reason to 'awkward synonyms': they
are usually similar in form, as are 
militate
 and 
mitigate
, and sometimes even
pronounced the same, as are 
principal
 and 
principle
, but are very different in meaning.
