… issue some would prefer to observe in silence (8)

I believe the answer is:

children

'issue' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for children that I've seen before include "Issue" , "Little people" , "Sons and daughters" , "Small people" , "Youngsters" .)

I've seen this clue in The Guardian.
