Cryptic Double Definitions
Double definitions, or DDs, are a basic clue-type as they simply provide two different definitions of the same word with a surface reading that aims to mislead the solver into thinking of something other than the answer.
They can be as simple as two words:
Yellow layer? (7)
yellow = chicken (as in cowardly)
layer? = chicken (as in one that lays ... eggs)
Or be made up of phrases or more than a single word as we have seen in:
Capital city in Georgia (6)
capital = ATHENS (Greek capital)
city in Georgia = ATHENS (city in Georgia, USA)
NOTE: DDs normally have two different meanings of the same word, but sometimes, as with CAPITAL CITY IN GEORGIA the setter may feel the two meanings are sufficiently different to be ok - in this case one is a city, and the other a capital.
Double definitions can also be extended to triple, quadruple, quintuple definitions and more.
Cryptic DDs follow the same format as normal DDs, but either one or both of the definitions used will be cryptic.
Here is an example of a DD with one cryptic and one standard definition:
A useful outback skill - landing strip maintenance? (9)
A useful outback skill - BUSHCRAFT
landing strip maintenance? - BUSHCRAFT
Note how the 2nd definition cryptically and whimsically defines the word BUSHCRAFT. It leads the solver to think of the importance of keeping a remote airstrip in good working order - however, when we think of a LANDING STRIP as a type of pubic hair design we can see that BUSHCRAFT is indeed a good definition.
