I found that assurity is not available in the online https://dictionary.cambridge.org/
But I did find it on https://www.urbandictionary.com/ . Is this proper English words
Do Americans or Canadians use it? I have heard this word from non-native English speakers

    'Assurity' isn't in Lexico either (Oxford Dictionary) but, I found it here – a Caribbean dialect word meaning : firm promise. Mar 24, 2022 at 7:44

  • As Weather Vane says Assurity is a Caribbean dialect word. However, there are some companies that use it in their corporate name such as Assurity Consulting who are a long way from the Caribbean being in West Sussex UK. There are others. Maybe where you've seen it it should have been assurance which is used in a very similar way in BrE. Caribbean : "You have my assurity that I will pay you tomorrow" means the same as BrE : "You have my assurance I will pay you tomorrow". In other words, a firm promise of payment.

  • @WeatherVane Not sure that one anonymous post on some website is proof enough. Some should pick up a phone and call, say, the Jamaican Consulate or embassy in their area. That's how to do this sort of thing. Or Trinidad and Tobago. The Caribbean is very diversified.

  • @Lambie then it's a good thing that I didn't post an answer. It's still not a "proper English word." The Lexico link is broken but it's not in Cambridge dictionary. Nov 13 at 16:25

The word normally used is 'surety', which is probably where it evolved from in the Caribbean, (from 'a surety'). But used to mean 'being sure' is an archaic or obsolete use of the term now; though it can still be found in places like the KJ bible, (in Job 13 for instance).
