3.9 Hyphenation of Unit Modifiers<br />

3.9.1 Hyphenate unit modifiers in order to avoid ambiguity. Unit modifiers are two or more words<br />

used as an adjective. They may consist of any of the following:<br />

adjective + noun: high-speed printers long-term bonds a part-time job<br />

noun + adjective: age-old problem tax-exempt status ice-cold water<br />

noun + participle: law-abiding citizen interest-bearing account pear-shaped drop<br />

adjective + participle: high-ranking official smooth-talking operator half-baked idea<br />

adj. + noun + ed: flat-footed player full-bodied brew medium-sized room<br />

adverb + participle: well-known method ever-changing winds much-needed hit<br />

participle + adverb: worn-out equipment scaled-down proposal cooling-off phase<br />

number + unit of measure: 25-g sample 5-cm thickness 2.5-ms delay<br />

number + unit of measure + word: 3-year-old child 4-mm-thick layer<br />

phrasal compound: up-to-date figures step-by-step directions would-be expert<br />

Note: A number of adjective–noun combinations (such as real estate) and noun–noun<br />

combinations (such as life insurance) are actually well-established compound nouns serving as<br />

adjectives. Since such expressions refer to well-known concepts or institutions and are easily<br />

grasped as a unit, they do not require a hyphen.<br />

social security number life insurance policy nuclear energy plan real estate tax<br />

Note: Individual journals may elect not to hyphenate unit modifiers consisting of a number and an<br />

abbreviated unit of measure:<br />

5 nm spacing 2500 Å wavelength 557.7 nm emission at 60 km altitude<br />

Consult the given journal’s appendix for specific cases.<br />

3.9.2 Hyphenate unit modifiers used as predicate adjectives. In general, only unit modifiers that<br />

consist of nouns and adjectives can be used as predicate adjectives.<br />

In these cluster reactions, dehydrogenation is size-dependent.<br />

The reaction is first-order.<br />

3.9.3. Do not hyphenate unit modifiers in the following instances:<br />

(1) if the first word is an adverb ending in -ly or very;<br />

recently developed procedure a very well studied hypothesis<br />

(2) if the unit modifier is a chemical name;<br />
