It's bearing your weight so do not shake it (5,2)

'it's bearing your weight' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'so do not shake it' is the wordplay.
'so' becomes 'stood' (I am not sure about this - if you are sure you should believe this answer much more).
'do' indicates anagramming the letters (solvers must work out or 'do' the anagram puzzle).
'shake' indicates named letters should be taken away.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'not' with 't' taken out is 'no'.
'no' anagrammed gives 'on'.
'stood'+'on'='STOOD ON'

Can you help me to learn more?
