1 someone whose job is to write the words for advertisements:
copywriter for sth After completing a degree in journalism he took a job as a copywriter for an advertising agency.
And the copywriter would presumably avoid such ambiguities anyway.
Some advertising copywriter is making a good living out of cleverly worded advertisements of this kind.
After all, we do need lawyers and phsysicists, advertising copywriters, computer programmers and so on.
Here there are opportunities for unscrupulous exploitation of the consumer, because the consumer buys purely against illustration and the persuasive wording of highly-skilled copywriters.
That is necessary in the interests of the viewing public, and certainly necessary as a guide to the copywriter, the advertiser and the advertising agent.
An exaggerated fear has been expressed today about the difficulty and trouble that the copywriters will have by complete equality of treatment being required.
Perhaps the copywriters will take that up; perhaps they will not.
I am sure that a copywriter could make marvellous propaganda out of this which would induce people to save.
