Superlative: crossest
The word 'crossest' is derived from 'cross' (from Old English 'cros', meaning a structure consisting of an upright and a transverse piece) and the superlative suffix '-est' (meaning most). Therefore, 'crossest' refers to the state of being most cross or angry.
Think of the word 'cross' as a structure that represents anger, and the '-est' indicates the highest degree. So, 'crossest' means the most angry.
