Stratagem? Tense account about it relayed back (6)
I believe the answer is:
tactic
'stratagem?' is the definition.
(I've seen this before)
'tense account about it relayed back' is the wordplay.
'tense' becomes 't' (abbreviation used in many dictionaries).
'account' becomes 'acc'.
'about it' means one lot of letters goes inside another (some letters go around or about others).
'relayed back' becomes 'ti' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'acc' going around 'ti' is 'actic'.
't'+'actic'='TACTIC'
Can you help me to learn more?
(Other definitions for tactic that I've seen before include "Plan, manoeuvre" , "Planned manoeuvre or skilful move" , "Manoeuvre, stratagem" , "Ploy, strategem" , "element of strategy" .)
