Both of these verbs are used for asking about something or looking for information. The nouns for the request / investigation are enquiry and inquiry.

Technically, enquire is used for "ask" in general ("He enquired about prices for the products"), and inquire for a more formal investigation ("The police will make an inquiry into the alleged corruption.")

However, in American English it is now very common to use inquire for everything: "He inquired about prices for the products."

Precautions while using Securing Email

Visit the website of the email provider of your choice

If you choose to use Gmail, simply visit www.gmail.com. The website for Yahoo! Mail is mail.yahoo.com, and Outlook is simply www.outlook.com. A good password will contain a combination of uppercase and lowercase letters; numbers; and/or special characters such as %, $, and +. It is very important to keep your password private at all times. A password that contains a mixture of letters and numbers is a good way of securing your password.
