What does rotatable mean?
Rotatable is an adjective describing something that can be turned around an axis or otherwise reoriented. It is especially common in technical descriptions of equipment: a rotatable screen, platform, antenna, or housing may be adjusted to suit the user's position or the direction of a signal. The word does not imply that the object moves continuously; it indicates that the object's orientation can be changed. A rotating display, by contrast, turns automatically or as part of a regular cycle. Rotatable is therefore useful when the distinction between being adjustable and continuously revolving matters. It appears in ordinary consumer language as well as engineering, product design, and instructional writing, without a strong formal or informal stigma and with essentially the same usage in British and American English.

"The monitor has a rotatable screen that can be positioned for either portrait or landscape viewing."
"A rotatable display can be angled so that it is easier to view from different positions."
"The technician adjusted the rotatable antenna until it faced the strongest signal."
A rotatable object does not have to move by itself; it simply has the freedom to be turned.
