Are You Steady?

This morning during my prayer time I noticed how steady the candle flame was, burning straight and quietly. Maybe I noticed because the other day I had a candle so flickering and fluttering I had to blow it out. I was beginning to feel dizzy and ill even if I didn't look at it directly.

I'm fascinated by words and as I thought about the steadiness of the candle flame I wondered where the word came from and about it's meaning. I got this from an etymology site:

steady(adj.)

1520s, "firmly fixed in place or station" (displacing earlier steadfast, which came to be used of persons and characters), from stead + adjectival suffix -y (2), perhaps on model of Middle Dutch, Middle Low German stadig.
