The classic meaning of “blatant” is “noisily conspicuous,” but it has long been extended to any objectionable obviousness. A person engaging in blatant behavior is usually behaving in a highly objectionable manner, being brazen. Unfortunately, many people nowadays think that “blatant” simply means “obvious” and use it in a positive sense, as in “Kim wrote a blatantly brilliant paper.” Use “blatant” or “blatantly” only when you think the people you are talking about should be ashamed of themselves.
2) BONAFIED / BONA FIDE
Bona fide is a Latin phrase meaning “in good faith,” most often used to mean “genuine” today. It is often misspelled as if it were the past tense of an imaginary verb: “bonify.”
3) BORN OUT OF / BORN OF
Write “my love of dance was born of my viewing old Ginger Rogers-Fred Astaire movies,” not “born out of.” The latter expression is probably substituted because of confusion with the expression “borne out” as in “my concerns about having another office party were borne out when Mr. Peabody spilled his beer into the fax machine.” The only correct (if antiquated) use of “born out of” is in the phrase “born out of wedlock.”
In some dialects it is common to substitute “borrow” for “loan” or “lend,” as in “borrow me that hammer of yours, will you, Jeb?” In standard English the person providing an item can loan it; but the person receiving it borrows it.
For “loan” vs. “lend, see “Non-Errors.”
There are times when it is important to use “each” instead of “both.” Few people will be confused if you say “I gave both of the boys a baseball glove,” meaning “I gave both of the boys baseball gloves” because it is unlikely that two boys would be expected to share one glove; but you risk confusion if you say “I gave both of the boys $50.” It is possible to construe this sentence as meaning that the boys shared the same $50 gift. “I gave each of the boys $50” is clearer.
