Dramatically in short, it's curtains for some baker's batch/turnover (4)
I believe the answer is:
tabs
'dramatically in short it's curtains for some baker's batchturnover' is the definition.
I can't tell whether this defines the answer.
'in short it's curtains for some baker's batchturnover' is the wordplay.
'in' indicates putting letters inside.
'short it' becomes 't' (abbreviation. e.g. in 'tis; 'short' suggests a short form).
'curtains for' suggests removing the centre (the edge letters are curtains around the word).
'some baker's' becomes 'bakers'.
'batchturnover' becomes 'a' (I can't explain this - if you can you should believe this answer much more).
'bakers' with its middle taken out is 'bs'.
't'+'bs'='tbs'
'tbs' enclosing 'a' is 'TABS'.
Can you help me to learn more?
(Other definitions for tabs that I've seen before include "It's curtains" , "Bills in restaurants" , "Marks in computer document" , "medication" , "that are picked up by footers?" .)
