Does to shut sb out mean to ignore sb by leaving the place where one is, ore purely ignoring sb? Can I shut sth out?
If you shut someone out, it normally means that you are ignoring them or that you are purposely not including them in something. You don't need to actually leave the place where you are.
You can shut someone out even if you are in the same room as them. For example, if there are 3 people in the room, and 2 of them are having a conversation, they can make it very obvious that they don't want the third person to join in, by ignoring everything they say or simply never directing the conversation to them. Those 2 people would be "shutting the other person out".
You can also be "shut out of your house" - if the door closes behind you, and you have forgotten your keys, then you are shut out (or locked out).
I may well be corrected by an American here, but I believe that if, in sport (hockey, for instance?), one of the teams has scored no points then the other team has achieved a "shutout". The winning team successfully stopped their opponents from scoring at all.
