Silver Porsche's behind following along street towards the house (9)
I believe the answer is:
downstage
'towards the house' is the definition.
I can't judge whether this definition defines the answer.
'silver porsche's behind following along street' is the wordplay.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'behind' says to take the final letters.
'following' means one lot of letters go next to another.
'along' becomes 'down' (synonyms).
'street' becomes 'st' (abbreviation).
The final letter of 'porsche' is 'e'.
'ag'+'e'='age'
'down'+'st'='downst'
'age' after 'downst' is 'DOWNSTAGE'.
Can you help me to learn more?
(Other definitions for downstage that I've seen before include "near to house?" , "Coach from London once" , "theatrical direction" , "Forward, as player" , "closest to house" .)
