To 'share' something in common

[PrincessFiorimonde]

Is that ok? Or should it be: to 'have' something in common?

To 'share' something in common - a usage which I've seen quite a lot - seems a bit odd to me (isn't it tautological?), but am happy to be corrected.

Have something in common

or

Share common interests

I'm not an expert, but 'share something in common' doesn't sound quite right.

I agree.

If something is 'in common', by definition it is being shared. So I think it would be "Have something in common" or "Have common interests".
You could concievably 'share something' or 'share interests' or 'have shared interests', but I don't think any of those are as good for that particular purpose.

At a slight tangent (should that be 'at' or 'on'), 'share' seems to have gone a bit management-speak-y. We 'share' learning objective with pupils, and I think that's an utter travesty. I just tell them what they are.

Sharing - management speak
Fairness - government speak.

Time was when these were for small children....

Thanks all for your comments. Will continue to change 'share something in common' to 'have something in common' every time I can!
