Girl is excited with the French window fixture (6)
I believe the answer is:
grille
'window fixture' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'girl is excited with the french' is the wordplay.
'is excited' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'the french' becomes 'le'.
'girl' anagrammed gives 'gril'.
'gril'+'le'='GRILLE'
Can you help me to learn more?
(Other definitions for grille that I've seen before include "Grating, metal screen" , "Metal lattice" , "Frame of bars" , "Part of an air-cooling system" , "A metal grating in door or window" .)
