Work by LS Lowry principally means I mostly see factory features (8,5)
I believe the answer is:
assembly lines
'factory features' is the definition.
(factories contain assembly lines)
'work by ls lowry principally means i mostly' is the wordplay.
I cannot quite see how this works, but
'work' could be 'line' (line can mean someone's profession or work) and 'line' is located in the answer.
'i' could be 'a' and 'a' is found in the answer.
This explanation may well be incorrect...
'see' acts as a link.
Can you help me to learn more?
(Another definition for assembly lines that I've seen is " Factory arrangements of workers and machines".)
