cai2
means 'talent'
cai2
originally was a hieroglyph. The horizontal stroke is the ground, the vertical
one being the stem and the left sliding stroke, the root. The whole thing
describes 'the prospect for growth'.
cai2 neng2 means 'ability' and
literally translates as 'talent'-'capable'.
neng2
originated from the hieroglyph

sense of 'capability' and 'power' was derived from the animal's features.
tian1 cai2 means 'genius' and
literally translates as 'heaven'-'talent'.
tian1
is derived from
.
The first character is ren 'man' (a stick figure of a walking
person). With arms stretched out, man looks overwhelming in size and so
the middle character da means 'big'. But what is superior
to all? The answer is 'heaven' and therefore da with a top
horizontal stroke (indicating above man) becomes tian meaning
'heaven'.
