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

'make similar sounds everyone repeats' is the definition.
I can't tell whether this defines the answer.

'everyone repeats' is the wordplay.
'everyone' becomes 'all' (all people).
'repeats' becomes 'iterate' (I can't explain this - if you can you should believe this answer much more).
'all'+'iterate'='ALLITERATE'

Can you help me to learn more?

(Other definitions for alliterate that I've seen before include "put with a lot of bees?" , "say bollocks to Brexit?" .)
