'increasing pressure' is the definition.
Although both the answer and definition are present participle verbs, I can't see how one could define the other.

'troubled ipl seemingly? no? yes' is the wordplay.
'troubled' indicates an anagram.
'no?' indicates named letters should be taken away.
'ipl'+'seemingly'='iplseemingly'
'iplseemingly' with 'yes' removed is 'iplemingl'.
'iplemingl' with letters rearranged gives 'IMPELLING'.
