You
will fi nd them in many sentences. These words generalize a fact. There are certainly
exceptions. Ask them:
?– Really always? Really everybody? Really never?
The general situation is often correctly mapped to a system. It is the exception
that causes problems. In my car, e.g., the navigation system ??™ s display is linked to
the car light. When I switch the headlights on the display switches automatically
to night mode, which is better readable in the dark. Now, it is customary in my
area to drive with the lights on during the day too. The display in night mode is
then rather hard to read.
An acquaintance of mine has a habit of putting his briefcase on the passenger
seat. Then, however, the car refuses to start driving. It expects the passenger to
buckle up fi rst.
I ??™ m sure that you have made similar experiences with a system in exceptional
cases.
You can recognize conditions in words like if , then , unless , provided that ,
depends . They describe variants. Ask for completeness:
?– Are there other variants? What if not?
A condition is a junction that leads to something else.
