To a point, basic education about love is a mistake (5)
I believe the answer is:
error
'is a mistake' is the definition.
(I've seen this before)
'to a point basic education about love' is the wordplay.
'to a point' becomes 'e' (compass point).
'basic education' becomes 'rrr' (the three R's - reading, writing and arithmetic).
'about' means one lot of letters goes inside another.
'love' becomes 'o' (love means zero in tennis).
'rrr' going around 'o' is 'rror'.
'e'+'rror'='ERROR'
(Other definitions for error that I've seen before include "A mistake or inaccuracy" , "Bug" , "Boob" , "Faux pas" , "Way of operating" .)
