It's a simple little word, yet it conveys so much. To me it means, warm, safe, loved, cosseted, enveloped, pampered. It reminds me of when I was a wee girl and sick and Mom would make up the sofa with my bed pillow and heavy wool blankets (you know, the pretty cream ones with pastel stripes) and bring me ginger ale and chicken soup while I watched daytime TV. I much prefer the word spelled with a z (not an s). It seems more onomatopeic that way. These pictures say cozy to me.
