My goodness! I type wrongly (5)
I believe the answer is:
piety
'my goodness' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'i type wrongly' is the wordplay.
'wrongly' is an anagram indicator.
'i'+'type'='itype'
'itype' with letters rearranged gives 'PIETY'.
Can you help me to learn more?
(Other definitions for piety that I've seen before include "Godly behaviour" , "Quality of being religious" , "Holiness" , "Attentive religious practice" , "Devotion to religious principles" .)
