Queer Street resounded with the last of these (7)
I believe the answer is:
strange
'queer' is the definition.
('strange' can be similar in meaning to 'queer')
'street resounded with the last of these' is the wordplay.
'street' becomes 'st'.
'resounded' becomes 'rang' ('ring' can be a synonym of 'resound').
'with' means one lot of letters go next to another.
'the last of' indicates one should take the final letters.
The last letter of 'these' is 'e'.
'st'+'rang'+'e'='STRANGE'
(Other definitions for strange that I've seen before include "Peculiar; Morse's boss" , "Extraordinary" , "Irregular" , "Unknown or peculiar" , "Singular" .)
