The quality or state of being beady; the characteristic of having small, round, bright eyes; the appearance or manner of beads.
From beady + -ness (Old English suffix forming abstract nouns from adjectives). The -ness suffix abstractifies qualities into countable concepts.
The -ness suffix is English's secret weapon for turning feelings and qualities into concrete nouns—from 'beautiful' to 'beauty' to 'beautifulness,' it lets us noun almost any adjective, giving us 'beadiness' from 'beady.'
