Stroll is walking slowly for pleasure, with nowhere you have to be. Add -er and you get the one that strolls: sometimes the person doing the ambling, sometimes the thing that goes along with them. Every meaning on this page still has that walking pace somewhere inside it.
可以想成 stroll（不趕時間、慢慢走）加上 -er（做這件事的人或東西）。合起來就是「跟慢慢走有關的那一個」。有時候指走路的那個人，有時候指陪著一起走的那樣東西。這一頁上的每個意思裡，都還留著那個「不急、慢慢走」的速度。
From the word’s history
The source records the word as stroll + -er, so it begins as nothing more than 'one that strolls'. That starting point is still visible in the person walking and in the seat an adult pushes at walking pace.
來源資料把這個字記成 stroll 加 -er，所以它一開始的意思就只是「做 stroll 這件事的那一個」。這個起點到今天都還看得見：一邊是慢慢走的人，一邊是大人用散步的速度推著走的那台車。
