Odd oratress has rows (4)
I believe the answer is:
oars
'rows' is the definition.
(I've seen this before)
'odd oratress' is the wordplay.
'odd' indicates alternate letters.
The alternating letters of 'oratress' are 'OARS'.
'has' acts as a link.
(Other definitions for oars that I've seen before include "Soar with propellors" , "Paddles" , "rows" , "Manually operated boat propellers" , "Rowing blades" .)
