I was unable to understand the similarities and differences between intent and purport. A description will be good to understand.
"Purport" usually has a negative connotation of falsely conveying a certain meaning while "Intent" is more neutral.
The purport of this book is to present an objective take on abortion, although in actual fact, it leans heavily on anti-abortion viewpoints.
The intent of this book is to present an objective take on abortion.
As reported from the NOAD, the meaning of the words, when used as nouns, is the following:
The meaning of purport as verb is "appear or claim to be or do something, especially falsely", "profess".
Intent is a concept that shapes action, but it is not action.
Purport, as a noun, means to carry or transmit the gist of something, either literally or implicitly.
As a transitive verb, purport gives voice to 3rd person hearsay (as in report) rather than direct transmission, and is usually interpreted as supposed or alleged.
Very interesting question about the dual meaning of purport. I'm not sure how intent is involved.
