This Troublesome Pair was suggested by a reader of one of my previous posts. Do keep your suggestions coming if there’s one you are confused about yourself or notice other people mixing up!
Wonder and wander is probably another pair that gets mixed up because the two words sound (fairly) similar, or exactly the same in some accents.
To wander is to move around aimlessly, to walk or move in a leisurely manner through or over an area. You might “wander lonely as a cloud” across the Lake District, for example (thanks to Wordsworth). A wander (the noun) is an aimless walk.
To wonder is to feel curious or desire to know, or to feel wonder, as in surprise and admiration caused by something unfamiliar, unexpected or beautiful (wonder (noun) being that feeling). “The sunset caused a sense of wonder in the onlookers”; “Mary wondered where her lamb had got to”.
To distinguish the two: “Mary wandered all over the farm, wondering where she had left her lamb”.
