Generosity refers to a readiness or liberality in giving, and sometimes to an overall spirit of kindness. Another way to name generous giving, when it involves gifts or money, is with the noun largess. Largess can also refer to the gifts themselves. At the root of largess is the word "large," so one way to think about it is that those who show largess are characterized by the largeness of their contributions, monetary or otherwise. Most commonly, you will see largess used in the public works sense, denoting a sense of superiority or higher rank on the part of the one or ones bestowing it.
We may be searching last minute for those trinkets to stuff a stocking with or to decorate our homes right now. A trinket is a small ornament or piece of jewelry, often of little value. When the trinket is showy or cheaply made, and typically round, it may be called a bauble. Bauble originally referred to the staff or scepter that a court jester carried, and later to something pleasing to a child, like a toy. Bauble can simply be used to refer to a small, spherical ornament that is hung from the branches of a Christmas tree. So gather your trinkets, doodads, gewgaws, trifles, and baubles, and start decorating!
To share is to have a share or part in something, divide it equally, or grant partial use of it. In the digital realm, share means to give specific users access to your online content. The verb partake also implies sharing (of an event, feeling, or experience—particularly a meal), but highlights the recipient and the taking (not giving) of something. Partake is a back formation from partaking, from the Middle English phrase “part taking,” meaning "taking part." If partaking of or in something sounds a little lofty, there's good reason! Partake is a very old word in English, first recorded in the middle of the 16th century.
