Love to take tea break about five. Like an egg? (5)
I believe the answer is:
ovate
'like an egg?' is the definition.
(I've seen this before)
'love to take tea break about five' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'to take' means one lot of letters go next to another.
'break' indicates an anagram.
'about' means one lot of letters goes inside another.
'five' becomes 'V' (Roman numeral).
'tea' with letters rearranged gives 'ate'.
'ate' enclosing 'v' is 'vate'.
'o'+'vate'='OVATE'
(Other definitions for ovate that I've seen before include "Egg-shaped, oval" , "philosopher" , "Egg-shaped - eisteddfodic graduate" , "Shaped like an egg" , "applaud enthusiastically?" .)
