The word "sip" refers to the act of taking a small amount of liquid into the mouth, typically by using a straw or the lips of a cup or glass. It often implies a slow or gentle way of drinking, allowing the person to savor the taste or avoid gulping down the liquid quickly.
The word "sip" comes from Middle English "sippen," which is derived from Old English "sippian." This is related to further roots indicating a small amount of liquid. The word has been in use for centuries and reflects a similar concept across various Germanic languages.
