Accommodates husband and old applications (6)
I believe the answer is:
houses
'accommodates' is the definition.
(I've seen this before)
'husband and old applications' is the wordplay.
'husband' becomes 'h'.
'and' says to put letters next to each other.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'applications' becomes 'uses' (I've seen this before).
'h'+'o'+'uses'='HOUSES'
(Other definitions for houses that I've seen before include "Residences" , "Accommodates" , "As safe as these dwellings" , "Royal families" .)
