Eight in a row? (7)
I believe the answer is:
oarsmen
'eight in a' is the definition.
I can't judge whether this definition defines the answer.
'row?' is the wordplay.
I cannot really see how this works, but
'row?' could be 'oar' (oar can mean to row with oars) and 'oar' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oarsmen that I've seen before include "They propel boats manually" , "Scullers" , "Strokes" , "Rowing types" , "They row boats" .)
