Questions & Answers about Hon delade med sig av sin kunskap.
Why use delade med sig av instead of just delade?
While dela on its own means to divide or share a physical thing (like a pizza or a bill), the phrasal verb dela med sig means to generously share something you possess with others. When you specify what is being shared, particularly abstract concepts like knowledge or experiences, you use dela med sig av.
Why do we need the preposition av here?
In the expression dela med sig, the preposition av is used to introduce the specific thing being shared. You can think of it as sharing a portion 'of' her knowledge. If you didn't mention what she was sharing, you would drop it and just say hon delade med sig (she shared).
Does the word sig change if the subject of the sentence changes?
Yes, it does. Because sig is a reflexive pronoun, it has to match the subject doing the action. If the sentence started with 'I', it would be Jag delade med mig av..., and for 'you' it would be Du delade med dig av....
Why is it sin kunskap and not hennes kunskap?
