Eleemosynary is quite daunting with its rather peculiar pronunciation and long string of letters. However, once you get to know eleemosynary, it is pretty nice–in fact, it loves to donate. This is because the adjective denotes something charitable or inclined to donation.
The first form of this word comes from the Greek eleemosune, compassion, and then the Latin eleemosyna. Some people thought eleemosynary was too long (for whatever reason), so it was anglicized to the shorter and more common alms.
