ladder, stairs, insatiable drinking
梯 centers on a structure for climbing step by step: a ladder or stairs. The rare sense of insatiable drinking is a figurative extension of climbing or escalating consumption.
梯 combines 木 (tree/wood) with 弟, which likely contributes the sound and the idea of order or sequence, suggesting a wooden structure with ordered steps.
The left side 木 suggests wood, and the right side 弟 looks like a series of steps or rungs. Picture a wooden ladder made from a tree, with each rung like a younger brother following in order.
For テイ, imagine climbing a ladder to take a tea break: tea -> テイ, and you reach the top step for a sip.
