Grandpa's prepared to swallow pill and somehow try to make do with fresh air? (6,5)
I believe the answer is:
garden party
'somehow try to make do with fresh air?' is the definition.
I can't judge whether this defines the answer.
'grandpa's prepared to swallow pill' is the wordplay.
I cannot quite see how this works, but
'pill' could be 'e' (ecstasy) and 'e' is found in the answer.
an anagram of 'grandpa' is 'gardnpa' which is within the left over letters.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for garden party that I've seen before include "Formal festive outdoor occasion" , "Lawn event" , "Social occasion at Buckingham Palace, perhaps" , "Alfresco social event" , "Buckingham Palace event" .)
