Such a clock has a dial, if only outwardly (7)
I believe the answer is:
digital
'only outwardly' is the definition.
I can't tell whether this definition defines the answer.
'such a clock has a dial' is the wordplay.
'such a clock' becomes 'dial' (I've seen this before).
'has' indicates putting letters inside.
'a dial' becomes 'git' (I can't explain this - if you can you should believe this answer much more).
'dial' enclosing 'git' is 'DIGITAL'.
'if' is the link.
Can you help me to learn more?
(Other definitions for digital that I've seen before include "of modern clock?" , "Works with through numerals, like watch" , "finger" , "form of technology" , "Sort of radio" .)
