Tolkien delighted in certain kinds of jocular wordplay. He seems to have enjoyed extending ordinary words by adding a suffix which did not quite 'fit', as for example with staggerment, a word of which he was particularly fond. ... He had a particular weakness for such forms of verbal whimsy when he was consciously writing for children, as in The Father Christmas Letters (a 'thinnuous elf', a pun on fatuous) or Roverandom ('the rhymeroyals and the pennywhistles, the tintrumpets and the creamhorns, a very pale cream'). The same rather avuncular vein runs through both The Hobbit (confusticate and bebother) and the early drafts of the opening of its sequel (HME VI. 11ff.), where we find flabbergastation, grabsome, and vanishment. Such coinages were weeded out as it became clear that The Lord of the Rings was to be more serious in intent. - Gilliver, P. et. al. (2006).
