Rubbish initially appearing in Times (3)
I believe the answer is:
tat
'rubbish' is the definition.
(low-quality items or material)
'initially appearing in times' is the wordplay.
'initially' says to take the initial letters.
'in' means one lot of letters goes inside another.
'times' becomes 'tt' (an abbreviation for time written twice).
The first letter of 'appearing' is 'a'.
'a' going inside 'tt' is 'TAT'.
(Other definitions for tat that I've seen before include "Cheap rubbish" , "Inferior articles" , "Utterly tasteless objects" , "Cheap and vulgar tastelessness" , "Tawdry or shabby articles" .)
