Chirk is a verb that means to make cheerful or lively.

Our word of the day was born in the Middle English period as a sound made to cheer people up. It’s been a part of English language ever since. Here’s an example of chirk in use:The sound of the ice cream man’s music chirked in the early afternoon air. It brought a smile to my face because it evoked childhood memories of chasing down the ice cream man for several blocks.
