What does it mean when it surrounds a word in red? Is this signalling an error?

Try Lower casing, my phone tried to capitalize and it was a problem.

Seems to be a word not in its dictionary. Seems to not have any country or language names.

Edit: these must be capitalized to be recognized.

Yes, word in red = word not found mostly the case when you try plurals or non-nouns (for now)

[rpastuszak]

This is neat!

I think you need to disable auto-capitalisation because on mobile the first word becomes uppercase and triggers a validation error.
