Get into a row (5)
I believe the answer is:
align
'row' is the definition.
(thesaurus)
'get into a' is the wordplay.
'get' becomes 'lig' (I can't explain this - if you can you should believe this answer much more).
'into' is an insertion indicator.
'a' becomes 'an'.
'lig' going inside 'an' is 'ALIGN'.
Can you help me to learn more?
(Other definitions for align that I've seen before include "Put in correct positions" , "Put into a straight row" , "Regulate, arrange in line" , "Adjust -coordinate" , "Straighten in relation to others" .)
