The verb inquire means "to ask for information." If you wonder about how the world began, you inquire about its origin.
Inquire comes from the Latin combination of words in, meaning "into" and quærere, meaning "ask, seek." When you inquire, you look into something. You might ask a question, like inquiring if the bakery is hiring any cake decorators. Inquire can also mean "to conduct an investigation." No matter how you do it, when you inquire, you seek answers.
