worship

Worship comes from Middle English worschippe/worthschipe, which comes from Old English weorþsċiepe. By surface analysis it breaks down into wor(th) plus -ship, the same suffix that turns qualities into states, as in friendship.

The facts available don't describe a shift in meaning over time, just the word's descent from Old English through Middle English into modern form.

It's cognate with Scots worschip, which carries the same meaning, showing how closely Scots and English preserved this old word side by side.
