There's nothing wrong with genuflecting, which is the sort of upright curtsy done by some people if they need to pass in front of an especially holy bit of a church.
A genuflecter may possibly come over as a bit of an exhibitionist, and it's certainly hard on the knees, but. hey, if that's what people want to do...
Nevertheless, the word itself is horrible.
Genuflect. It sounds like a technical term for a stomach complaint. Why can't there be a nice simple old word for paying respect to God in this way?
It's enough to make one wonder if genuflecting was originally a rather unEnglish form of showing off.
Word Not To Use Today: genuflect. This word comes from the late Latin genuflectere, from Latin genu knee and flectere to bend. It was first used in English in 1630.
