Truss support for royal male say (8)

I believe the answer is:

kingpost

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

'male say' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'truss support for royal' is the wordplay.
'truss support' becomes 'post' (I can't explain this - if you can you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'royal' becomes 'king' (a king is royal).
'post' put after 'king' is 'KINGPOST'.

Can you help me to learn more?
