'one deduces' is the definition.
(I've seen this in another clue)

'are possibly close relations' is the wordplay.
'possibly' indicates an anagram.
'close relations' becomes 'sons' (son is a kind of relation. I am not sure about the 'close' bit.).
'are' anagrammed gives 'rea'.
'rea'+'sons'='REASONS'

Can you help me to learn more?

(Other definitions for reasons that I've seen before include "Rational motives" , "Debates; thinks out" , "excuses" , "Period of reduced economic activity" , "Logically deduces" .)
