A Slot is issued by Air Traffic when the airspace becomes limited by the amount of traffic using it or other restrictions. A Slot is given as a designated time UTC, the slot window is a 15 min period from 5 mins before to 10 mins after this designated time. If the aircraft fails to get airborne within this 15 minute window – it means moving to the back of the que for another slot! or maybe it’s time to re-file another flight plan, using an alternative (not so busy) route!!

Window seat is correct. Sometimes the restrictions are due to weather at the destination airfield, either due to bad visibility, snow, etc, or even just due to parking restrictions. With regard to bad visibility limits are sometimes placed on aircraft that can accept RVR’s of less than a certain distance, say 400m.
En route restrictions may apply to aircraft routing through certain sectors that may be busier than normal.
Occasionally, areas of airspace are closed due military activity. This sometimes has the effect of placing greater demand on neighbouring sectors because of flights being re-routed.
Often traffic is subject to an MDI [minimum departure interval] through a particular piece of airspace. That may be one movement every 4 mins, for example. This is can be applied suddenly and may be because of sector overload.
At the end of the day slot times are a safety net used to maintain separation of aircraft and ease the traffic load on controllers. It is easier to plan the separation on the ground than when the flight is airbourne.
I am sure others may add to this.
