Physical laziness left feeling of annoyance we hear (7)

I believe the answer is:

languor

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

'physical laziness' is the definition.
'languor' can be an answer for 'laziness' (I have seen 'Mental laziness' mean 'languor' so perhaps 'laziness' could also mean 'languor'). I'm not certain of the 'physical' bit.

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for languor that I've seen before include "Apathy" , "Mental laziness" , "Enervation" , "Weakness - sluggishness" , "Lack of vitality, listlessness" .)

I've seen this clue in The Times.
