Cockney & Eastenders
Cockney and east end clues can make up the whole or part of the answer word. They play on the way the cockney accent drops the letter H and so are used to subtract H from a bit of fodder. They can also be used as homophones which subtract H as well as sound alike and may also indicated cockney rhyming slang is being sought.
Let's look at two examples:
To go from HOSKINS to OSKINS, the setter may write:
Cockney Hoskins ...
... here, COCKNEY is the indicator which tells the setter to drop the H in HOSKINS to leave OSKINS.
To get FACE from BOAT, the setter may write:
Boat according to a Pearly King ...
... here, ACCORDING TO A PEARLY KING, is the cockney indicator. It helps show the solver cockney rhyming slang is need to go from BOAT to FACE (boat race is CRS for face).
Any word or phrase that fairly indicates a cockney usage may be used as a cockney indicator. Here are some more examples:
