Which options are ok to say spell etc?

[°Leprechaun]

Of the first 17 choices, which are all right.
*Obviously unless you are extremely literal the last three apply to choosing more than one or other options. There are many other possible options so I would like to see them added to the list.

is anyone else slightly confused?

Which so called "politically incorrect" phrases (eg there are two genders") are fine?
Certain words are misspelled. Some are obvious.
Other choices like to boldly split an infinitve are considered bad grammar. People often confuse who and whom or I and me. Maybe it is confusing because there are three different categories.
They all have to do with how language has been changed. English is not an easy language. Spelling is not phonetic.

Spell checker catches some spelling errors.

Also there are many who don't like the expression "multiple personality disorder".. perhaps it is considered insensitive.
