If the audience can trust the speaker, then they can believe the speaker whereas when the speaker has poor reputation or does not appear to be trustworthy, then the audience will be less likely to listen to him as he speaks.
Terminal Credibility is a type of a credibility where the speaker has either gained or lost <em>afte</em>r delivering a speech. it is like the lasting impression that the audience has for the speaker. in the case of Frederick, He attained Terminal credibility since the audience came forward <em>after </em>he had completed his speech and told him they found his speech useful. It is terminal credibility because it was when he had completed his speech that the audience came forward to give their opinion. not during the speech like in derived credibility nor before the speech like in initial credibility.

If people get to trust you at the end as when they approach Frederick at the end of the speech ,this is referred to as terminal credibility. This means he was able to establish that trust in the end of his speech.
Terminal credibility is your last impression, if it gains you trust from your audience that means you have achieved it.
