The first sense that appears in my test concordance is "a bit", so I looked it up in the BSL.
This is strictly speaking "correct", in that the hierarchy is a single node (adverbs don't have hierarchical relationships), but not helpful: i'll file a case to suppress the "Type of" display in such cases.
Some adverbs have pertainym relationships (like eagerly), so i think we should leave the Relationships section even if it's currently empty: hopefully more relationship will get added over time (though i'm "a bit" uncertain what relationships to add here).
Thanks - that makes sense
