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.

Reticent means “disposed to be silent or not to speak freely.” This tight-lipped adjective is more specific than its synonym reserved, which is widely used of both speech and actions and implies a guardedness born of caution or a sense of formality. Reticent simply describes people who aren’t inclined to chatter. A word to the wise: reticent is used to mean “reluctant” with some regularity, but style guides urge against this broad interpretation in favor of the more precise application.
