Can I use this sign for 'around' when talking about time?
While this sign is perfect for physical space (like 'around here'), talking about time usually uses a different sign for 'about' or 'approximately,' where the dominant index finger circles a pinched non-dominant hand.
Does the direction of the circle matter?
Most signers naturally make the circle outward and then inward toward their body, but the exact direction isn't strictly important as long as it is a smooth, flat, horizontal circle.
How big should the circle be?
A medium-sized circle, roughly the size of a dinner plate, is standard. Making the circle much larger might imply a very vast or wide-reaching area.
