'training habit' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'we shed tears about' is the wordplay.

an anagram of 'tears' is 'sater' which is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?
