[en] Columbia/Colombia (Word confusion)

[Tex2002ans]

Columbia->Colombia

These coins came from Great Britain, Portugal, Spain, France, Brazil, Mexico, Chile, Peru, Columbia, and Bolivia.

• Colombia = the South American country
• Columbia = a river and a few cities

Also from Lexico:

• British Columbia
• District of Columbia

https://www.lexico.com/en/definition/british_columbia https://www.lexico.com/en/definition/district_of_columbia

and probably:

• Columbia River

Columbia (with a 'u')

Definitely valid:

• Columbia University https://www.lexico.com/definition/columbia_university

• British Columbia https://www.merriam-webster.com/dictionary/British%20Columbia

• District of Columbia https://www.merriam-webster.com/dictionary/District%20of%20Columbia

• Columbia River https://en.wikipedia.org/wiki/Columbia_River

(Should there be a huge/broad rule covering large rivers?)

• Columbia County Seems like there's many (mostly in the US): https://en.wikipedia.org/wiki/Columbia_County

Columbian (with a 'u')

Definitely valid:

• British Columbian (a person from British Columbia [demonym]) https://www.lexico.com/definition/british_columbian

Colombian (with an 'o')

• Colombian Search for "Colombian *" in Google Web 1T 5-Gram Database

• "Colombian peso" = definitely valid. https://en.wikipedia.org/wiki/Colombian_peso

(Unsure if there's completely separate rules for money? Since pesos/dollars are used in multiple countries.) https://www.merriam-webster.com/dictionary/peso

Definitely should point towards the 'o' version:

• military/drug/coffee

but I'm unsure on:

• emerald

From Google searches, it looks like the 'u' version is an extremely common typo, but I don't know if it's an actual/separate type of emerald.

Google hits:

• 1,070,000 = Colombian emerald

• 330,000 = Columbian emerald

• • -

I'm thinking any other usages of:

• Colombia<->Columbia
• Colombian<->Columbian

should be marked as a potential "word confusion".
