Encountered outside Iran, perhaps inside mosques too (7)
I believe the answer is:
minaret
'mosques too' is the definition.
I can't judge whether this definition defines the answer.
'encountered outside iran perhaps' is the wordplay.
'encountered' becomes 'met' ('meet' can be a synonym of 'encounter').
'outside' indicates putting letters inside.
'perhaps' indicates anagramming the letters.
'iran' anagrammed gives 'inar'.
'met' going around 'inar' is 'MINARET'.
'inside' is the link.
Can you help me to learn more?
(Other definitions for minaret that I've seen before include "Appropriate raiment for mosque tower" , "Slim tower of a mosque" , "Mosque spire" , "Mosque's tower" , "Muezzin's tower" .)
