In a manner that is full of dismay; disappointingly or discragingly.
The adverbial form of 'dismayful', created by adding '-ly' to the adjective. This represents a deeper layer of word-formation: dismay → dismayful → dismayfully.
Stacked suffixes like 'dismayfully' show how English creates subtle shades of meaning—but they also show why language prefers simpler paths. Speakers would just say 'disappointingly' rather than 'dismayfully', making this an evolutionary dead-end word.
