Simple language used by developer? (5)
I believe the answer is:
basic
'simple' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for basic that I've seen before include "Elementary - without extras" , "Elemental" , "Fundamental; alkaline" , "Fundamental, elementary" , "Simple form of language" .)
