-ly

Several adverbs which in modern English would end in -ly appear without the suffix in Shakespearean English. In most cases, adverb forms with the -ly are also found at that time - nobly, for example, in RJ III.v.181, damnably in 1H4 IV.ii.12; but audible (see below) is a case where the -ly form seems not to have entered English until later (earliest Oxford English Dictionary citation, 1635).

The opposite effect can also be seen: some adverbs were formed from nouns with the -ly suffix, such as angerly (KJ IV.i.81) and hungerly (Oth III.iv.101), which today have developed alternative forms (angrily, hungrily).
