Partner that is hiding runs for level ground? (7)
I believe the answer is:
prairie
'level ground?' is the definition.
'prairie' can be an answer for 'ground?' (thesaurus). I am not sure about the 'level' bit.
'partner that is hiding runs' is the wordplay.
'partner' becomes 'pair' (both can mean to form a pairing).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'hiding' indicates putting letters inside.
'runs' becomes 'r' (cricket abbreviation).
'pair'+'ie'='pairie'
'pairie' going around 'r' is 'PRAIRIE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for prairie that I've seen before include "Large treeless tract of grassland" , "Barren plain" , "American plain" , "Great grassland area" , "Schooners once crossed it" .)
