Fat Lao is swimming, buoyantly in water (6)
I believe the answer is:
afloat
'fat lao is swimming buoyantly in water' is the definition.
I can't tell whether this defines the answer.
'fat lao is swimming' is the wordplay.
'is swimming' is an anagram indicator.
'fat'+'lao'='fatlao'
'fatlao' is an anagram of 'AFLOAT'.
Can you help me to learn more?
