Mother takes a Glaswegian to be a talisman (6)
I believe the answer is:
mascot
'a talisman' is the definition.
(synonyms)
'mother takes a glaswegian' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'takes' means one lot of letters go next to another.
'a glaswegian' becomes 'scot' (I've seen this in another clue).
'ma'+'scot'='MASCOT'
'to be' acts as a link.
(Other definitions for mascot that I've seen before include "Something considered to bring good luck" , "It's adopted, by a team say, as a symbol" , "Thing believed to bring good luck, perhaps to team" , "Charm - talisman" , "Symbolic lucky figure" .)
