Extra time to follow chaps who do yoga? (10)
I believe the answer is:
supplement
'extra time to follow chaps who do yoga?' is the definition.
'supplement' can be an answer for 'extra' (I've seen this before). I'm not certain of the rest of the definition.
'extra time to follow chaps' is the wordplay.
'extra' becomes 'supple' (I can't justify this - if you can you should believe this answer much more).
'time' becomes 't' (abbreviation).
'to follow' means one lot of letters go next to another.
'chaps' becomes 'men' (chap means a man).
't' put after 'men' is 'ment'.
'supple'+'ment'='SUPPLEMENT'
Can you help me to learn more?
(Other definitions for supplement that I've seen before include "Add-on" , "Add to (something)" , "addition" , "something to remedy a deficiency" , "Boost" .)
