March, say, around oil rig in a massive column (8)
I believe the answer is:
monolith
'massive column' is the definition.
'monolith' can be an answer for 'column' (thesaurus). I'm not certain of the 'massive' bit.
'march say around oil rig' is the wordplay.
'march say' becomes 'month' (march is a kind of month).
'around' indicates putting letters inside.
'rig' is an anagram indicator (I've seen 'rigged' mean this).
'oil' is an anagram of 'oli'.
'month' placed around 'oli' is 'MONOLITH'.
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for monolith that I've seen before include "Big pillar" , "Monument of a single standing stone" , "Monument of a large standing stone" , "Statue from one block of stone" , "Single great stone, column or obelisk say" .)
