Build on root words using falling morphemes: prefixes, suffixes, compounds and blends.
Morphemes fall; you catch the ones that combine with your root and grow the longest, strangest, most legitimate words you can. 'Unaccountable' may feel awkward as a series of sounds, but it is perfectly logical as a combination of meaningful parts — and that is exactly the logic MegaMorph trains.
Morphology: how English words are built and taken apart — free and bound morphemes, roots, prefixes, suffixes. The recognition process that fluent reading is built on.
