Problems for lots of children (6)
I believe the answer is:
issues
This might be a double definition.
'problems' is the first definition.
(I've seen this before)
'lots of children' is the second definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's a link between them I don't understand?
'for' acts as a link.
Can you help me to learn more?
(Other definitions for issues that I've seen before include "Questions to be resolved" , "Brings out a publication" , "collected numbers" , "Individual editions" , "'Editions, publications (6)'" .)
