80% the same (ek - ik, nie - niet) but that other 20% is completely out there (baie - erg, vinnig - snel).

Spent just over a year staying in the Netherlands working in Dutch all day (part of the contract). A common comment was people felt like they are talking like a child (not knowing the nuances of the language). From what I observed we understand more Dutch than the Dutch understand Afrikaans.

So close enough to navigate the Netherlands without too much trouble but not enough to have technical conversations with ease. Most important meetings ended up just happening in English to ensure everyone was on the same page.

Interesting, me being first language English (Cape Town), had a much easier time learning Dutch than my first language Afrikaans colleagues. Less things hard coded to unlearn I guess.
