Unable to see, daughter dropping one pancake (5)
I believe the answer is:
blini
'pancake' is the definition.
(blini is a kind of pancake)
'unable to see daughter dropping one' is the wordplay.
'unable to see' becomes 'blind' (I've seen this before).
'daughter' becomes 'd' (genealogical abbreviation).
'dropping' is a deletion indicator (some letters drop out).
'one' becomes 'i' (Roman numeral).
'blind' with 'd' removed is 'blin'.
'blin'+'i'='BLINI'
(Other definitions for blini that I've seen before include "East European pancakes" , "Russian pancakes" , "Straw hat" , "Buckwheat pancakes" , "Eastern European twenty four Ac" .)
