Strangely, Trump (no politician) has use for this intellectual tome (9)
I believe the answer is:
thesaurus
'this intellectual tome' is the definition.
(type of reference book)
'strangely trump no politician has use' is the wordplay.
'strangely' indicates an anagram.
'no' is a deletion indicator.
'politician' becomes 'pm' (short for prime minister).
'trump' with 'pm' removed is 'tru'.
'tru'+'has'+'use'='truhasuse'
'truhasuse' with letters rearranged gives 'THESAURUS'.
'for' is the link.
(Other definitions for thesaurus that I've seen before include "Wordy gathering" , "Wordy book" , "work we may refer to" , "Volume of synonyms" , "Book listing synonyms" .)
