Thanks but it did not work. 
I am using emacs (28) master

I overwrote my complete fundamental-mode-abbrev-table
with your suggestion and restarted emacs
(BTW edit-abbrev did not show the regexp)

In any case 

 a que was not expanded to a qué 

To make matter worse, I added your suggestion to my old
fundamental-mode-abbrev-table restarted emacs and then *nothing* was

I am puzzled
