Ducking autocomplete

Dear Lazyweb, can anyone tell me how to make my Mac stop doing this incredibly unhelpful thing that it just started doing a couple of days ago? There is no "Learn spelling" menu item. Attempting the obvious thing in Preferences / Keyboard / Text says "The original text cannot contain spaces". Note that I am not asking "how do I turn off autocorrect".
