Explanation
Used to connect an い-adjective to a verb, modifying the verb (adverbial usage).
Formation
い-Adjective (remove い) + く + Verb
Detailed explanation
The い-Adjective + く + Verb grammar point transforms an い-adjective into its adverbial form, describing how the verb is performed. In English, this often corresponds to '-ly' adverbs (e.g., 'quickly', 'slowly').
