Baby's bed found in street by one quiet Glaswegian, say (8)
I believe the answer is:
scottish
'glaswegian say' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'baby's bed found in street by one quiet' is the wordplay.
'baby's bed' becomes 'cot' (cot is a kind of baby's bed).
'found in' indicates putting letters inside.
'street' becomes 'st' (abbreviation).
'by one' becomes 'i' (Roman numeral. I am not sure about the 'by' bit.).
'quiet' becomes 'sh' ('sh' is used to tell someone to be quiet).
'cot' placed into 'st' is 'scott'.
'scott'+'i'+'sh'='SCOTTISH'
Can you help me to learn more?
(Other definitions for scottish that I've seen before include "northern folk" , "Caledonian" , "So stitch up to be like Angus or Jock" , "From the northern UK" , "Costs hit this nationality badly" .)
