'jam' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'trouble bishop breaking nail' is the wordplay.
'trouble' becomes 'ail' (synonyms).
'bishop' becomes 'B' (chess abbreviation).
'breaking' is an insertion indicator.
'nail' becomes 'tack' (tack is a kind of nail).
'ail'+'b'='ailb'
'ailb' inserted within 'tack' is 'TAILBACK'.

'in' acts as a link.
