I feel that I am using the verb "to be" too much in my formal writing and hence I am trying to find a formal substitute that I can use from time to time. Could the verb "to constitute" be such a synonym?
For example, if I were to say (dumb examples, I know)...
A car is a vehicle
A car constitutes a vehicle
...would both sentences mean the same? Is = constitutes?
Other dumb examples:
The law of gravitation is a first approach to the problem
The law of gravitation constitutes a first approach to the problem
Lying is an immoral act
Lying constitutes an immoral act
