Some bottle-openers in house (3)
I believe the answer is:
leo
'house' is the definition.
(Leo is an astrological house in the zodiac)
'some bottle-openers in' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'LEO' is hidden in the letters of 'bottle openers in'.
(Other definitions for leo that I've seen before include "Zodiacal lion" , "Name taken by 13 popes, the last dying in 1903 aged 93" , "Lion sign of the Zodiac" , "sign of summer" , "house" .)
