Definitions

[1] Listing of Definitions

Descriptions of meaning and usage for indigenous Japanese words in ordinary use are generally offered in the historical order of their occurrences in the usage examples cited.
Descriptions of basic predicates generally proceed from a general overview of basic meanings to explanations of more specific meanings.
Descriptions of technical terms, names of things and affairs, and the like consist primarily of definitions of the words, but may also extend to explanations of the matters or affairs themselves as required.

[2] Symbols used in Definitions

The following four kinds of serial symbols are employed to mark the sense- and usage-divisions of an entry, as appropriate for specific levels of explanation.

【一】【二】 …… are for use in dividing senses and usages on the basis of grammatical factors, such as part of speech, distinction between transitive and intransitive verb forms, type of inflection or conjugation, etc.

〔一〕〔二〕 …… are for use when an entry takes on basic senses that differ significantly from each other, when significantly different kanji renditions are customarily in use, or when pronouns grouped under a single entry are distinguished from each other.

(1)(2) …… are generally for use in dividing definitions.

(イ)(ロ) …… are for use in subdividing definitions to further elucidate, in particular, differences among gender-, age-, occupation-, or class-specific senses and usages.
