Yahoo period in email
You're referring to the "at symbol" or "ampersand" in an email address!
In an email address, the period (.) is not typically used as a separator between the username and the domain name. Instead, the "at symbol" (@) is used to separate the two parts.
For example:
In this example, "username" is the part before the @ symbol, and "domain.com" is the part after the @ symbol.
The period (.) is sometimes used in domain names to separate subdomains or to indicate a specific top-level domain (TLD). For example:
- example.co.uk (the period separates the subdomain "example" from the TLD "co.uk")
However, in an email address, the period is not used as a separator between the username and the domain name. The @ symbol is the standard separator used in most email addresses.
