I believe the answer is:

knight

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'give a touching' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'display of regal appreciation' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

Can you help me to learn more?

(Other definitions for knight that I've seen before include "In Britain, a person honoured by the sovereign for personal merit" , "He's a Sir in the UK" , "- - errant" , "Give title to; chess piece" , "Dub" .)
