In Afrikaans, verbs usually do not change according to the subject in the present tense the way they do in English.
So you get:
English changes have to has with he/she/it, but Afrikaans keeps het.
Soveel means so much or so many.
In this sentence, because werk is an uncountable noun, the natural English translation is so much work.
Compare:
So soveel can work with both countable and uncountable nouns.
Here werk means work in the general, uncountable sense, just like in English.
You would not normally pluralize it in this meaning.
Werke does exist, but it usually means works in a more specific sense, such as literary works, artistic works, or separate pieces/projects in certain contexts. In everyday speech about being busy, werk is the normal word.
Because werk here is being used as an uncountable noun, just like English work.
English says:
not usually She has a work.
Afrikaans works the same way here:
So no article is needed.
A rough guide for an English speaker:
A very rough whole-sentence approximation might be:
say het suh-FAIL verk
This is only approximate, but it can help as a starting point.
Normally, no.
In this sentence, werk means work as an uncountable noun, not jobs.
If you wanted to say She has so many jobs, you would usually need a countable noun, for example something like soveel poste or another context-specific word for jobs/positions.
So Sy het soveel werk is understood as She has so much work, meaning she is very busy.
