This is a grammar question regarding the verb, CONSERVE. Webster’s dictionary says it is a transitive verb, and I have always heard it used in the transitive sense, for example,
I conserve fuel.â€
But, I have just heard a laboratory researcher use it in the intransitive sense:
In light of the evolutionary process, the organ system in the fruit fly, like the organ system in the human, is conserved throughout evolution.â€
Is Webster’s dictionary incorrect? Should the dictionary list CONSERVE as both transitive and intransitive?
