This sentence works differently in English and Dutch. With gaan you have to add some specifics (probably because gaan is also used to make a future tense). The only exception, where you can use gaan without accompanying words is in the meaning of going away. Some examples:
- Ik ga = Ik ga er vandoor = Ik ga weg = I'm going away/I'm leaving
- Ik ga niet = I'm not going away/I'm not going to whatever is specified before
- ik ga er niet heen = I'm not going to whatever is specified before
- Ik eet = I eat
- Ik ga eten = I am going to eat
- Ik ga daar eten = I'm going to eat there
- Ik ga daar (this is an incomplete sentence, some additional word has to follow)
- Ik ga daar naartoe = Ik ga daar heen = I go there
"Were" is the subjunctive. It is used to "express[...] a circumstance which is desired, demanded, recommended, necessary, or similar." https://en.wikipedia.org/wiki/English_subjunctive In this case, it refers to something that is contrary to fact (NOT in the intial tips) that is desired ("it would be nice..."). Subjunctive forms are often the same as indicative forms in modern English so people are not always aware of the distinction, and the mood is falling out of use.
For the people who have made the same mistake as I did, which mistaken “everyday" with "every day", here is what I learned:
everyday is one single word and it is only an [adjective], so it should only be used before the nouns. Before, I thought it could also be an [adverb], but that is WRONG.
every day, on the other hand, is equal to "each day", thus can be used as an [adverb].
In Duolingo sometimes the miss of a space is allowed, but I am now in line with the spirit of this question: the difference is fundamental
If you don't conclude with naartoe, people will be expecting that the sentence isn't finished. The specific sentence we are discussing doesn't lend itself well to an example so here is what this sounds like in English:
He goes every day to
Difference here is that in Dutch, it sounds weird and confusing when you leave out a different word versus in English.
Hope this helps!
