This is the adverb: in a presentable way — tidy and neat enough to be seen. You dress presentably, or leave a kitchen presentably clean. It does the same job as presentable, but it tells you how something is done or how it looks, rather than naming the quality itself. Students meet it much less often than presentable; many speakers simply say “look presentable” and never use the -ly form at all. It is ordinary English, a little formal in the way adverbs of this kind often are.
