Workers’ group overlooking impudent talk in plant (5)
I believe the answer is:
tulip
'in plant' is the definition.
'tulip' can be an answer for 'plant' (I've seen this before). I am unsure of the 'in' bit.
'workers' group overlooking impudent talk' is the wordplay.
'workers' group' becomes 'tu' (short for trade union).
'overlooking' means one lot of letters go next to another (in a down clue, some letters go above others).
'impudent talk' becomes 'lip' (informal term for impolite remarks).
'tu'+'lip'='TULIP'
Can you help me to learn more?
(Other definitions for tulip that I've seen before include "Flower - lit up (anag)" , "Spring-blooming plant" , "Dutch bulb?" , "Plant at the centre of the Dutch financial bubble of 1637" , "Pretty flower, musically from Amsterdam" .)
