15.1a Single italic sign.

To indicate that only one word, hyphenated compound word or expression, abbreviation, or number is in a special typeface, a single italic sign is placed before it. The effect of the italic sign continues until the reader encounters a blank cell or a slash. For that reason the italic sign is not repeated after the hyphen in a compound word, after an apostrophe, or after the first period in an unspaced abbreviation, but is repeated after a space or a slash. Note that the italic sign is placed before the capital sign. Examples:
