Record of a governess left in Siam (5)
I believe the answer is:
annal
'record' is the definition.
(I've seen this in another clue)
'a governess left in siam' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is found in the answer.
'left' could be 'al' (I've seen this in other clues) and 'al' is found in the answer.
A single letter 'n' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for annal that I've seen before include "Record of a year's events" , "Yearly record" , "record shows" , "A record in a chronicle" , "Record of one year" .)
