加拿大ispell词典有什么区别

Aspell项目旨在替代 ispell，并使用相同的英语词典（可能对其他语言也使用相同的词典）。我下载了最新版本的英文词典aspell6-en-2020.12.07-0.tar.bz2，它包含一个名为的文件extra.txt，用于解释不同的词典。总结文件：

• en_CA = en_CA-wo_accents。这本词典对每个单词都有一个“最被接受”的拼写。它不包括重音符号，即 é、è 和所有其他重音符号 'e' 仅显示为 'e'
• en_CA-w_accents 与上面相同，但在每个字母上都包含相关的重音符号
• en_CA-variant_0 包括某些单词的多个拼写，当这些拼写在加拿大英语中同样被接受时。它是 en_CA 的超集
• en_CA-variant_1 包含更多不那么标准的多种拼写。它是 en_CA-variant_0 的超集

对于那些对整个解释感兴趣的人：

 INFORMATION ON THE PROVIDED DICTIONARIES

This word list package supports the following dialects of English:

  American (en_US)
  British with "ise" spelling (en_GB-ise)
  British with "ize" spelling (en_GB-ize)
  Canadian (en_CA)

In addition generic English (en) is supported which is a combination
of all the above.

For each dialect there is the option to either strip accents (for
example cafe) or keep them (for example café).  The default is to
strip them.

Combining these two options gives the following dictionaries.  

  en_US-wo_accents
  en_US-w_accents
  en_GB-ise-wo_accents
  en_GB-ise-w_accents
  en_GB-ize-wo_accents
  en_GB-ize-w_accents
  en_CA-wo_accents
  en_CA-w_accents
  en-wo_accents
  en-w_accents

in addition to the following aliases:

  en_US = en_US-wo_accents
  en_GB = en_GB-ise-wo_accents
  en_GB-ise = en_GB-ise-wo_accents
  en_GB-ize = en_GB-ize-wo_accents
  en_GB-wo_accents = en_GB-ise-wo_accents
  en_GB-w_accents = en_GB-ize-w_accents
  en_CA = en_CA-wo_accents
  en = en-wo_accents

  american-* = en_US-*
  britsh-* = en_GB-*
  canadian-* = en_CA-*
  english-* = en-*

If you are using Aspell 0.60 these aliases can be changed locally via
"dict-alias" option.  For example if you prefer the "ize" spelling for
British English add the line:

  add-dict-alias en_GB en_GB-ize

to ".aspell.conf".

Great care has been taken so that that, for the most part, only one
spelling for any particular word is included in the main dictionary.
When two variants were considered equal I randomly picked one for
inclusion in the main word list.  Unfortunately this means that my
choice in how to spell a word may not match your choice.  For this
reason the following auxiliary dictionaries are provided:

  en_US-variant_0
  en_US-variant_1
  en_GB-variant_0
  en_GB-variant_1
  en_CA-variant_0
  en_CA-variant_1
  en-variant_2

These dictionaries are meant to be used in addition to one of the
standard dictionaries. To specify them use the "extra-dicts" option.
The "en_*-variant_0" dictionaries includes most variants which are
considered almost equal, "variant_1" includes variants which are
generally considered acceptable, and "variant_2" contains variants
which are seldom used and may not even be considered correct.  It is
only necessary to use on of these dictionaries since, for example,
"en_US-variant_1" includes all the words in "en_US-variant_0".


UPGRADING FROM ASPELL6-EN-0.01

If you are upgrading from the aspell6-en-0.01 package you should do a

  rm `aspell config dict-dir`/en[-_]*.alias

to remove any old alias.  Otherwise aspell may get confused as this
version installs the alias with the ".multi" extension instead of
the ".alias" extension.
