11.5 Special Rule for after, blind, and friend as Part Words [XVI.47.f]

These three words, when used as parts of words, are governed by the same rules as all the other short-form words if a consonant or a hyphen follows them. Examples:

afterbirth after-shave
blindness friendship

However, when the words after, blind or friend are followed by a vowel, the short forms cannot be used because they then take on the appearance of another word. For instance, if the short form for blind were used in blinded the result would be bled. If, however, such a word is divided between lines and the vowel falls on a new line, the short form is used. When appearing at the end of a line, it is permissible to use the short forms for after, blind, or friend. Examples:

blinded befriending aftereffects
blind-
ed.

befriend-
ing,

after-
effects
