Lands lots lay claim to (4)
I believe the answer is:
bags
'lands lots' is the definition.
'bags' can be an answer for 'lots' (bags of means lots). I'm not sure about the 'lands' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bags that I've seen before include "Holdalls" , "strides?" , "Flexible container" , "I claim" , "Containers for carrying, informally plenty" .)
