Underhanded
Often incorrectly used for underhand; as “That was a contemptible and underhanded trick.”
Calligraphy
This word means not writing, simply, but beautiful writing; hence, to say, “His calligraphy is wretched” is equivalent to saying, “His excellent writing is poor,” which is a contradiction of terms.
Can but, Cannot but
These expressions are sometimes confounded. “If I perish, I can but perish,” means “I can only perish,” or “I can do no more than perish.” “I cannot but speak of the things I have heard” means that I am under a moral necessity to speak of these things. The past tense forms could but and could not but should be, in like manner, discriminated.
Casualty, Casuality
The latter word is sometimes used in place of the former. The first is legitimate; the second is without authority. The words specialty and speciality have a termination similar to the above. They may generally be used interchangeably and are both legitimate.
“The lady is light complected, has blue eyes, and auburn hair.” Complected is a provincialism without sanction. “The lady is of light complexion, has blue eyes,” etc.
