OK Google: Urbanism is a word

I wrote someone an email recently, and in it I used the word “urbanism.” To my surprise, Gmail spellcheck underlined that word in red.

I tried other varieties. “Urban” does not get underlined. “Urbanization” is also OK. Even “urbanity” is in Google’s dictionary! So why is “urbanism” left out? “Urban” has been a Latin root word for anything related to cities for centuries. Tufts has a greatly detailed Latin dictionary.

The Odeon of Domitian, Ancient Rome.

What forces are at work here? I have a feeling that the answer is prosaic and disappointing. The answer may lie with how online spellcheckers work. My understanding is this: large online databases store lists of every known English word on their servers. Here’s Oracle’s (and an excerpt below):


Companies like Google can tap into that text, and use Java or Javascript to check a user’s input text against that list at the speed of the internet.  Google had its own attempt at a dictionary database called Google Dictionary, but it was discontinued in 2011. It was preserved in its unfinished state at this website. I typed in “urbanization” and got a hit. But then I typed in “urbanism” and got nothing!

WordPress also doesn’t recognize “urbanism” as a word, perhaps because it piggybacks its spellcheckers onto Google’s. Could Google have left some words behind when it migrated its database of English words in 2011?

One final note. The great irony is that Google’s parent company Alphabet has an urban planning subsidiary called Sidewalk Labs. Their well-publicized foray into using data to plan better cities already has a pilot project underway in Toronto, partnering with Thomas Heatherwick, Snøhetta, and other huge names in architecture & planning. Maybe it’s time for the leading innovators in urbanism to expand their vocabulary. I mean that in the least sarcastic way possible.
