expanding your vocabulary

I learned another new word today and you'll like this one.  The word is morganmuffel.  It's evidently of German origin although I'm sure I don't remember ever hearing it from any of my father's generation and they were all of German descent.  It means a person who is grumpy in the mornings and doesn't like to wake up early.  I have four teenage grandchildren who are all morganmuffels.  Or perhaps they are all morganmuffelish.  I'm really not sure of the correct usage.  And by the way, I am writing this on my new laptop.  My son toiled for almost six hours to get everything transferred from my old computer to the new and add some new programs.  Now everything can go to the cloud (wherever that is) and, with a little practice I can draw pictures.  I really appreciated all his hard work but he may be a little mroganmuffelish in the morning.
