Occasional sort of table? (10)
I believe the answer is:
periodical
'table?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'occasional sort' is the wordplay.
'occasional' becomes 'periodic' (I've seen this before).
'sort' becomes 'al' (I am not sure about this - if you are sure you should believe this answer much more).
'periodic'+'al'='PERIODICAL'
'of' is the link.
Can you help me to learn more?
(Other definitions for periodical that I've seen before include "Publication" , "Newspaper" , "Magazine" .)
