Egyptian character, grand lady pharaoh evacuated (5)
I believe the answer is:
glyph
'egyptian character' is the definition.
(as in Egyptian hieroglyphs)
'grand lady pharaoh evacuated' is the wordplay.
'grand' becomes 'G' (synonyms).
'lady' becomes 'ly' (I can't justify this - if you can you should give a lot more credence to this answer).
'evacuated' means to remove the middle letters.
'pharaoh' with its middle removed is 'ph'.
'g'+'ly'+'ph'='GLYPH'
(Other definitions for glyph that I've seen before include "Sculpted symbol" , "character in carving" , "Sculptured symbol; frieze groove" , "Sculptured character" .)
