Second highest position, say (5)
I believe the answer is:
speak
'position say' is the definition.
'speak' can be an answer for 'say' (synonyms). I'm not certain of the 'position' bit.
'second highest' is the wordplay.
'second' becomes 's' (common abbreviation).
'highest' becomes 'peak' (synonyms).
's'+'peak'='SPEAK'
Can you help me to learn more?
(Other definitions for speak that I've seen before include "Converse" , "Orate" , "Utter words" , "give a lecture" , "express" .)
