shift, move, turn
轉 centers on changing position or direction: shifting, moving, or turning. The idea covers both physical rotation and abstract transfer.
轉 combines 車 (vehicle, wheel) with 專, which likely contributes the sound and the idea of turning or revolving. The character originally referred to a wheel turning or a cart moving.
A vehicle 車 with a turning wheel 專: imagine a cart shifting direction as its wheels turn.
For テン, picture a cart turning ten times: ten -> テン, and each turn shifts its position.
