Speak the name, giving weight to it (8)
I believe the answer is:
announce
'speak' is the definition.
(thesaurus)
'name giving weight to it' is the wordplay.
'name' becomes 'Ann'.
'giving weight' becomes 'ounce' (ounce is a kind of weight. I am not sure about the 'giving' bit.).
'to it' says to put letters next to each other.
'ann'+'ounce'='ANNOUNCE'
'the' is the link.
Can you help me to learn more?
(Other definitions for announce that I've seen before include "Make known officially" , "Publicise" , "Make known publicly with no nuance" , "Formally declare" , "Report" .)
