I'm a parasite, but bring good cheer, A winter's kiss, banishing all fear. I hang in doorways, a festive sight, But beware my touch, or you might unite.

Drop my last, and people say I am meant to be broken. Add an s, and perhaps you have a royal court. All together, I measure or make laws.

Ancient keeper of the passing day, I speak through shadows, not through sway. No ticking heart, no winding key, yet sunlight still gives time through me.

When your injured doctors wraps you up with me if it's severe parents place me on minor wounds like cuts one brand has a nostalgic jingle for me

From woolly backs I’m gently shorn, to keep you cozy through the storm. Yet bear my name another way, and someone else may make you pay.
