For example the word "religion" is defined as :
- The belief in and worship of a superhuman controlling power, especially a personal God or gods
1.1 A particular system of faith and worship
1.2 A pursuit or interest followed with great devotion
The latter definitions seem to be broader. So a 'religion' that does not worship a super human controlling power (1), does not match the first definition, but does the others (1.1 & 1.2). Also, a 'religion' that matches the definition in 1.2, may not match the definition in 1.1.
If the definitions are independent, then the meaning of the word is dependent on the authors intent and context. However, if the meanings are dependent then any of the definitions being satisfied would classify something as a religion.
For example, is it incorrect for an author to say the Buddhism is not a religion, clarifying that the definition (1) is being used? Is something a religion only if it meets i) all of the definitions, ii) one of the definitions (chosen by the author) or iii) at least 1 one of the definitions (chosen by the author).
Is it correct for an author to decide the level of restriction of a words definition?
