In Dutch, there is a certain kind of grammatical mistake that is particularly frowned upon. It is, more or less, the worst kind of mistake you can make. Strangely enough, this is not because the rules governing this particular situation are so easy to follow, quite the opposite: it is a particularly nasty rule that can even confuse the most confident speller. (IE me 
It has to do with regular and irregular verbs. Depending on the situation, a verb like ‘antwoorden’ (to answer) may end up like this:
- ik gaf hem antwoord (lit. I gave him answer, I answered him)
- hij heeft zijn eigen vraag beantwoordt (lit. he has his own question answered, he answered his own question)
- ik antwoordde hem (lit. I answered * him.)
(If I messed up with any of these examples, I will probably have to hand in my passport. We Dutch are like piranhas in this respect: if one is caught bleeding, the rest will eat him alive. Still, I’ve been thinking about it for so long I got confused again… :smack:
So that’s three possible options for ‘antwoorden’. Other verbs may have OTHER options, including one or two t’s, also depending on whether you are speaking in the past or the present tense. In this case, any version of ‘antwoorden’ ending in a T is definitely wrong, though many Dutch would pronounce it specifically with a sharp t-sound at the end!
Of course, there is a ‘trick’ to help you with this. We use the distinctly weird expression ‘t Kofschip (including the T which would be some kind of abbreviation for ‘the’ except a kofschip isn’t anything in particular either so that doesn’t exactly help foreign speakers OR the Dutch) and if the root of the verb (that is, the version of the verb that comes after ‘I’, like I Walk in English except (sigh…) there you’d say I am walking rather than I Walk… are you starting to see why foreigners hardly ever get this right?) ends in a letter that is in ‘t Kofschip (not counting the o or the I, did I mention that?), the variation you need is likely to end with a t rather than a d.
Anyway, fuck this up and people will correct you even though they may already have seen or heard OTHERS correct you! It really is the worst kind of mistake you can make, especially if you are a journalist. And you’re bound too, because no spellchecker has yet been invented that can deal with this kind of shit. Still, your editor will probably get a few letters complaining about falling standards in his newspaper! Any errors like this in a job-application and you will never work for that company again, at least not behind a desk.
