# Definition Template

Keywords: SL description

This template creates and marks a page which is intended as a terse definition.

## Rationale

Such pages are useful because they allow a direct link to or alias for the definition of the term in question. Since Go Wiki does not allow an alias to link to an anchor, it is not helpful to use an alias linking to a larger page containing a definition of the term. Even were that possible, it could be hard to find the definition on a large screen, especially at the end of an article.[1]

Definition pages bring with them the dangers of:

• Redundancy: Many pages could describe the same thing, costing more effort to bring them to a high standard and keep them there.
• Inconsistency: If facts or policy change, redundant pages may become inconsistent, making it unclear what is correct.
• Fragmentation: Spreading explanations of closely related material over many pages may make it harder for the reader to form a complete picture of the topic.

For these reasons it can be desirable for definitions to be terse and for explanations and worked examples to be on another page. The definition should then refer to that page for the details.

This is not to say that it may not later prove better to reorganise the pages and move the exposition to the definition page, from which one should then of course remove the definition template.

## Usage

When calling this template, supply the following parameters:

• 1: The term being defined
• 2: The page providing detailed explanations
• 3: The wiki text defining the term (in complete sentences and paragraphs)

and optionally:

• section: The name of the section in which the term is defined.
• anchor: An anchor for the section (or part thereof) in which the term is defined.

### Examples

`“{{Definition
| Snail
| A __snail__ is a group which has bad shape because it develops slowly and leaves a gleaming trail of [bad aji] across the board.
`
`The term was coined during the first game of the second [jubango] between [Honinbo Dosaku] and [Gnu Go].
}}”
`

produces:

The main treatment of this is in the article Bad Shape.
See the Definition template for a rationale and recommendations for definition pages.

In [Combinatorial Game Theory], a __dominated option__ of a [combinatorial game] is an option for a player less favourable than another option for the same player; such options may be eliminated:
;:  {cancel 3, 4|-5, cancel (-4)} = {4|-5} 
}}
`

## Notes

[1] It would help to find the targeted anchor if Go Wiki used CSS? to specify some form of highlighting for it, such as:

`:target {
border: 2px solid Brown;
background-color: LightCyan;
}
`

but that is not the case. [88] I (Patrick Traill) originally created this for use in Dominated Option, but it turned out that Dominated Options (plural) already existed, so I made that page an alias. My original content is used in the examples above.
