Averse/adverse
While these terms are related in origin, according to the Oxford English Dictionary, they should not be substituted for one another. Whereas “adverse” describes something that is harmful or unfavourable (such as an “adverse effect” of a drug), “averse” refers to a negative feeling about something.
Historic/historical
“Historic” means an important event, whereas “historical” refers to something that happened in the past. So, not all historical events are historic.

Unique/special
When you tell someone you think they’re unique, you’re telling them they are one of a kind – and you can tell because of the “uni” at the beginning, which is Latin for “one of a kind.” Technically speaking, every person on earth is unique. If what you’re actually trying to say is that this person is important to you – or unusual or fascinating – go with the word “special.”
