But when the words follow the noun, the hyphen is omitted. The lawn is well kept. Methods up to date in every way.
Also adverbs ending in -ly are not ordinarily made into compound modifiers: nicely kept lawn, securely guarded treasure.
[b.] Use a hyphen between members of a compound noun when the second member is a preposition, or when the writing of two nouns solid or separately might confuse the meaning: runner-up, kick-off; letting-down of effort, son-in-law, jack-o'-lantern, Pedro was a bull-fighter, a woman-hater, Did you ever see a shoe-polish like this?
[c.] Use a hyphen in compound numbers from twenty-one to ninety-nine, and in fractions according to the following examples:
Twenty-three, eighty-nine; but one hundred and one. Twenty-third, one-hundred-and-first man. Three-fourths, four and two-thirds, thirty-hundredths, thirty-one hundredths.
But omit the hyphen in simple fractions when loosely used: Three quarters of my life are spent. One third of his fortune.
[d.] A hyphen is not used in the following common words: airship, altogether, anybody, baseball, basketball, everybody, football, goodby, herself, handbook, himself, inasmuch, itself, midnight, myself, nevertheless, nobody, nothing (but no one), nowadays, railroad, themselves, together, typewritten, wherever, without, workshop, yourself, newspaper, sunset.
[e.] For words that do not come within the scope of rules, consult an up-to-date dictionary. Compounds tend, with the passing of time, to grow together. Once men wrote steam boat, later steam-boat, and finally steamboat. New-coined words are usually hyphenated; old words are often written solid. The degree of intimacy between the parts of a compound word affects usage; thus we write sun-motor, but sunbeam; birth-rate, but birthday; cooling-room, but bedroom; non-conductor, but nonsense. The ease with which a vowel blends with the consonant of a syllable adjoining it affects usage; thus self-evident, but selfsame; non-existent, but nondescript; un-American, but unwise. Many compounds, however, are still uncontrolled by usage; whether they should be written as two words or one, whether with or without the hyphen, the dictionaries themselves do not agree.
