Welshman's platform (4)

Ross

I believe the answer is:

dais

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

'platform' is the definition.
(I know that dais is a type of platform)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for dais that I've seen before include "stage" , "stands on this?" , "Throne platform" , "Said (anag.)" , "stepping up here?" .)
