Making Adverbs with '-mente'
This word is made by taking the female form of the adjective 'única' (unique) and adding '-mente'. It works just like adding '-ly' to words in English.
Where to Put It
You usually place this word right before the thing you are limiting. For example: 'únicamente los lunes' (only on Mondays).
