'speed' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe you can see an association between them that I can't see?

'bless men in abnormal' is the wordplay.
'abnormal' is an anagram indicator.
'bless'+'men'+'in'='blessmenin'
'blessmenin' with letters rearranged gives 'NIMBLENESS'.

Can you help me to learn more?

(Other definitions for nimbleness that I've seen before include "Lightness of movement" , "Ability to move quickly and lightly" , "Grace" , "Agility" .)
