Sidney, Earl, Diana, Old Bob and Henry Rice, for example (4,4)
I believe the answer is:
side dish
'rice for example' is the definition.
(I've seen this in another clue)
'sidney earl diana old bob and henry' is the wordplay.
'sidney earl' becomes 'side' (I can't justify this - if you can you should believe this answer much more).
'diana' becomes 'Di' (Di is short for Diana).
'old bob' becomes 's' (abbreviation for bob or shilling used before s97s).
'and' means one lot of letters go next to another.
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'side'+'di'+'s'+'h'='SIDE-DISH'
Can you help me to learn more?
(Other definitions for side dish that I've seen before include "Supplementary item at table" , "extra food" , "Food item subordinate to the main one" , "It goes with a main course" , "Accompaniment at mealtime" .)
