Run into position, quietly giving update (6)
I believe the answer is:
sitrep
'update' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'run into position quietly' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'into' means one lot of letters goes inside another.
'position' becomes 'site' (site is a kind of position).
'quietly' becomes 'p' (p for piano and quiet).
'r' going into 'site' is 'sitre'.
'sitre'+'p'='SITREP'
'giving' is the link.
Can you help me to learn more?
(Other definitions for sitrep that I've seen before include "Report on current position (colloq.)" , "Italian family prominent in fifteenth and sixteenth century (Lucrezia -)" , "account by military" , "in which officers take an interest?" .)
