Yoga position for all in America (5)
I believe the answer is:
lotus
'yoga position' is the definition.
(I've seen this before)
'for all in america' is the wordplay.
'for all' becomes 'U' (Universal film certificate - suitable for all).
'in' is an insertion indicator.
'america' becomes 'lots' (I can't explain this - if you can you should give a lot more credence to this answer).
'u' placed into 'lots' is 'LOTUS'.
Can you help me to learn more?
(Other definitions for lotus that I've seen before include "Aquatic plant" , "Plant promoting forgetfulness" , "We forget having eaten this" , "Mythological fruit - lily" , "One of the lilies" .)
