Adverbs

Adverbs can be formed from adjectives. Those adjectives ending in –ος, or in –ύς, –ιά, –ύ, or in –ης, –α, –ικο, form adverbs ending –α. For example:
αργός = slow → αργά = slowly
σωστός = correct → σωστά = correctly
βαρύς = heavy → βαριά = heavily
μακρύς = long → μακριά = far away

Adjectives ending –ης and –ες form adverbs ending –ως. For example:
ακριβής = exact → ακριβώς = exactly
προφανής = obvious → προφανώς = obviously

There are exceptions:

πολύς = much, many → πολύ = very, much

Adverbs are usually used to specify manner, place, time, or quantity. Those specifying time can indicate a point in time (now, then, early, late), a frequency (often, occaisionally, rarely, usually), or other time concepts (again, always, all the time, never).
