About
The character "梯" structurally integrates the wood radical "木" to indicate its original material composition with the component "弟" serving primarily as a phonetic indicator while concurrently suggesting a conceptual association with sequential order, mirroring the evenly spaced rungs of a ladder. Its core meaning as a device for vertical ascent remained stable from early classical texts onward, yet the term gradually broadened to encompass stairways constructed from diverse materials and later mechanical means like escalators, paralleling advancements in technology. This semantic expansion also allowed "梯" to function metaphorically, representing any graded system or pathway facilitating advancement, thereby maintaining its fundamental notion of structured elevation through linguistic adaptation.
