Wonder vs wander

We very often confuse the pronunciation of the verbs wonder and wander, despite the fact we might well know their meaning.

I wonder if you really know what you want [ask yourself, 'preguntarse'].
I often wander around the city [go from one place to another without a purpose, 'vagar'].

Wonder is pronounced / ʌ /, and has the same vowel sound as fun, sun, run, son.
A lot of English words with the letter o are also pronounced / ʌ /: one, done, money, won, love.

Wander, on the other hand, is pronounced / ɒ / and has the same vowel sound as want, what, dog, job.
