Mail autocorrect suggests 'spreedsheet' for 'spreadsheet' on macOS

Not a question, simply documenting my frustrations somewhere as they seem to be neverending with regard to incorrect autocorrect suggestions.

Just now: spreadsheet (flagged with a blue underline) right click, suggestion: spreedsheet (oh how interesting, a new word, lets see what that means... it even shows up in the 'lookup' dialogue box with the correct definition for spreadsheet. Below spreedsheet is the German translation, here it shows the word 'spreadsheet')

I was not able to reproduce this and failed to take a screenshot, incorrectly assuming it would be back. So instead I leave you this gem:

Mail is checking that word with the wrong dictionary. The German line in Look Up is the clue. When spelling is set to Automatic it can flip language mid-message, and then spreadsheet stops looking like a real word. In Mail, open Settings, then Composing, and set spelling to U.S. English instead of Automatic. In System Settings > Keyboard, make sure English is the top input source too.

If spreadsheet is still underlined, Control-click it and choose Learn Spelling. If spreedsheet ever gets inserted, Control-click that and choose Unlearn Spelling.
