4d blasé - mostly about flat?
U_i_ _r_ _s_d (parse please)

[bookbinder]

unimpressed

Inimpressed

[bookbinder]

blasé = unimpressed; not impressed by anything.
pressed = flat.
uni = could be short for universal = mostly.

Thank you

Bookbinder, I'm wondering where the M comes from? I'm also not keen on getting 'uni' from 'mostly'. that seems a bit of a stretch.

[Gill55]

Must be impressed but still don't think the clue is good. M for mostly and pressed for flat but the uni seems superfluous to the clue!

[Neveracrossword]

I've got it - it's Minu(s) , most of the '-' in the clue" ! Reverse it,'about, so Unim' ' +pressed, flat.

Brilliant. So annoying when you can't parse them. Thanks.
