Caught a minor typo:

Columbia -> Colombia

The South American country is with 2 'o'.

https://en.wikipedia.org/wiki/Colombia

I reported that to LanguageTool a few days ago as well. A very common typo.

(I just made a pull request on Sigil's Github.)

A great explanation of how to use HTML language codes is in W3C's "Language tags in HTML and XML" + see the whole list of languages/regions.

HTML Lang + EPUB dc:language

For the most part, you'll only have a main language:

• en = English
• es = Spanish
• de = German
• [...]

Everything else beyond that is "extra". For example:

• es = Spanish
• es-AR = Spanish (Argentina)
• en = English
• en-US = English (United States)
• en-GB = English (British)
• en-GB-oxendict = English (British + Oxford English Dictionary)
  
  • which prefers "-ize" over "-ise" endings.
    
  • See Wikipedia article, "Oxford Spelling"

Dictionaries

Dictionary files also follow those naming conventions (like KevinH said). So:

• es_AR = a Spanish (Argentina) dictionary
• en_GB = a British dictionary
• en_GB-oxendict = a British (Oxford) dictionary

And like KevinH said, pretty much any dictionary file since forever would follow those conventions.

Side Note: Also, in the future, lots of other benefits can come from proper lang markup.

I wrote about a few possibilities back in 2018: "Two questions".

Multi-Language Spellchecking was just one piece (and I'm ecstatic it's been added to Calibre+Sigil after me beating the drums since 2016!!!).
