Form of accommodation assimilating second to create another (6)
I believe the answer is:
hostel
'form of accommodation' is the definition.
'hostel' can be an answer for 'accommodation' (I've seen this before). I'm unsure of the 'form of' bit.
'assimilating second to create another' is the wordplay.
'assimilating' indicates putting letters inside.
'second' becomes 's' (common abbreviation).
'create' is an anagram indicator.
'another' becomes 'hel' (I can't explain this - if you can you should give a lot more credence to this answer).
's'+'to'='sto'
'sto' with letters rearranged gives 'ost'.
'ost' placed within 'hel' is 'HOSTEL'.
Can you help me to learn more?
(Other definitions for hostel that I've seen before include "Cheap lodgings" , "Temporary home for the hiker" , "Temporary lodging" , "Residence, eg for students" , "Low-cost accommodation building" .)
