The quality or state of being fainthearted; cowardice, timidity, or lack of moral courage.
From 'fainthearted' plus the noun suffix '-ness,' which creates abstract nouns from adjectives. This suffix stacking ('faint' + 'heart' + '-ed' + '-ness') shows how English builds complex ideas.
The existence of this word shows that English speakers of the past took cowardice seriously enough to have a special five-syllable word for the personality trait itself—'faintheartedness' sounds much more serious than just 'cowardice.'
