twirl, twist, twiddle, wring
拈 centers on a small, controlled turning motion with the fingers: twirling, twisting, twiddling, or wringing something.
拈 combines 扌 (hand) with 占, which likely contributes the sound. The character expresses a twisting or twirling action done by hand.
The hand radical 扌 beside 占 suggests fingers occupied with a small object, twirling or twisting it between them.
For ネン, imagine twirling a pen between your fingers while thinking: pen -> ネン, and the hand twirls it.
