Could you please explain the difference in the use of prepositions "in" and "under" with the noun "condition"?
How their use affects the sence of the noun?
When referencing an object that has a property, it is in good condition.
When referencing an object that is experiencing some external force, then it is under extreme conditions.
"This car is in excellent condition"
"The man was under very stressful conditions at work"
