Sounds like one way in to worship (5)
I believe the answer is:
adore
'to worship' is the definition.
(I've seen this before)
'sounds like one way in' is the wordplay.
'sounds like' becomes 'dor' (I can't justify this - if you can you should give a lot more credence to this answer).
'one' becomes 'a' (a thing is one thing).
'way' becomes 'e' (Compass direction - East).
'in' is an insertion indicator.
'a'+'e'='ae'
'dor' placed inside 'ae' is 'ADORE'.
Can you help me to learn more?
(Other definitions for adore that I've seen before include "Respect deeply" , "Love, worship" , "Love (someone) deeply" , "Like a lot" , "Love to distraction" .)
