Cloth worker posed with members and officials (9-2-4)

'officials' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'cloth worker posed with members' is the subsidiary indication.
'cloth' becomes 'serge' (serge is a kind of cloth**).
'worker' becomes 'ant' (worker is a type of ant).
'posed' becomes 'sat' (sitting is a kind of posing).
'with' says to put letters next to each other.
'members' becomes 'arms' (arm is a kind of member).
'serge'+'ant'+'sat'+'arms'='sergeantsatarms'

'and' is the link.

Can you help me to learn more?
