sweeping

I'm a little stuck... Click here to teach me more about this clue!

'non-specific' is the definition.
Both the definition and answer are adjectives.
Maybe you can see a link between them that I don't see?

'leak in pipe' is the wordplay.
'leak' becomes 'weep' (I've seen this before).
'in' indicates putting letters inside.
'pipe' becomes 'sing' (pipe can mean to sing or chirp).
'weep' placed within 'sing' is 'SWEEPING'.

Can you help me to learn more?

(Other definitions for sweeping that I've seen before include "Extensive" , "Brushing; generalised" , "clearing the mess?" , "Using a broom" , "Wide in range or effect" .)
