Language of father in tattered jeans? English (8)
I believe the answer is:
japanese
'language' is the definition.
(Japanese is an example)
'father in tattered jeans? english' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'in' indicates putting letters inside.
'tattered' indicates anagramming the letters.
'english' becomes 'E' (abbreviation).
'jeans' anagrammed gives 'janes'.
'pa' put inside 'janes' is 'japanes'.
'japanes'+'e'='JAPANESE'
'of' acts as a link.
(Other definitions for japanese that I've seen before include "Language of Tokyo" , "national" , "Silly ape jeans of this nationality" , "From the Land of the Rising Sun" , "This nationality apes Jean" .)
