Difficult to deal with Hertfordshire town stores closing in July (6)
I believe the answer is:
trying
'difficult' is the definition.
(similar in meaning)
'hertfordshire town stores closing in july' is the wordplay.
'hertfordshire town' becomes 'tring' (town in Hertfordshire).
'stores' indicates putting letters inside.
'closing in july' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
'tring' placed around 'y' is 'TRYING'.
'to deal with' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for trying that I've seen before include "Exasperating" , "Doing one's best - annoying!" , "Tiresome" , "Attempting or irritating" , "Annoying; sampling" .)
