Here are some possible ways to sign "forever":
* "Always" sign: This is the most common way to sign "forever" and can be used in many contexts. It is a simple sign that involves holding your dominant hand palm out in front of you with your fingers slightly spread and moving it back and forth in a smooth motion.
* "Continue" sign: This sign can be used to indicate that something will continue without end, implying forever. You make the sign by making a "C" shape with your dominant hand and moving it forward and then back in a circular motion.
* "Eternity" sign: This sign is a more formal way to sign "forever" and is often used in religious contexts. It involves making a "V" shape with your fingers and then moving your hand upwards in a straight line.
Ultimately, the best way to sign "forever" is to use the sign that feels most natural and conveys the intended meaning.
