Wife having gone to Orleans regularly visited sailor (4)
I believe the answer is:
wren
'orleans regularly visited sailor' is the definition.
I can't judge whether this definition defines the answer.
'wife having gone to' is the wordplay.
'wife' becomes 'w' (abbreviation).
'having' says to put letters next to each other.
'gone to' becomes 'ren' (I am not sure about this - if you are sure you should believe this answer much more).
'w'+'ren'='WREN'
Can you help me to learn more?
(Other definitions for wren that I've seen before include "Tiny bird" , "She served" , "English church architect, d. 1723" , "serving girl" , "one leaving evidence all around London monument" .)
