Complex vs. complicated
Wrong: Don’t make it sound more complex than it is.
Right: Don’t make it sound more complicated than it is.
Both complex and complicated refer to things that are composed of many parts or are difficult to understand. To a large extent they’re synonyms. But there’s often a subtle difference in how the two words are used. Something that is complex is innately intricate or perplexing. On the other hand, a relatively simple process can be made complicated by poor directions. A nuclear reactor is complex, but trying to herd cats is perhaps more complicated than it is complex. Remember, artful writing is all about nuance.
Intrical vs. integral
Wrong: Clean water is an intrical part of the ecosystem.
Right: Clean water is an integral part of the ecosystem.
Intrical is simply a common misspelling (and mispronunciation) of integral.
