Covered entrance, current century, standing in Iberian city (7)
I believe the answer is:
portico
'covered entrance' is the definition.
(I've seen this before)
'current century standing in iberian city' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'standing' suggests taking the first letters.
'in' means one lot of letters goes inside another.
'iberian city' becomes 'porto' (Portuguese city).
The initial letter of 'century' is 'c'.
'i'+'c'='ic'
'ic' inserted into 'porto' is 'PORTICO'.
(Other definitions for portico that I've seen before include "Colonnade, covered porch" , "Covered porch, perhaps with columns" , "Zeno's teaching colonnade" , "Elaborate porch" , "Roofed porch" .)
