Ex-president absorbing one hard hit (7)
I believe the answer is:
triumph
'hit' is the definition.
(I've seen this before)
'ex-president absorbing one hard' is the wordplay.
'ex president' becomes 'trump' (Donald Trump. I am not sure about the 'ex' bit.).
'absorbing' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'trump' enclosing 'i' is 'triump'.
'triump'+'h'='TRIUMPH'
Can you help me to learn more?
(Other definitions for triumph that I've seen before include "Notable achievement" , "hit" , "Conquer, prevail" , "Exultant victory" , "beat the opposition!" .)
