one word · two words
Usage — not pronunciation
The rule
Many common expressions look like they could go either way, but only one form is correct — and a few pairs are correct as either one word or two, depending on what they mean. There's no single trick that covers every case, but a handful of patterns cover most of them.
Always ONE word
Always TWO words
Depends on meaning — both forms are correct
everyday / every day
everyday (one word) — adjective, sits right before a noun — "an everyday routine", "everyday low prices"
every day (two words) — means "each day" — "I exercise every day"
already / all ready
already (one word) — means "before now / previously" — "I already ate"
all ready (two words) — means "completely prepared" — "we are all ready to go". Test: if you can insert a word between "all" and "ready" ("all quite ready"), it's this two-word phrase.
maybe / may be
maybe (one word) — means "perhaps" — "maybe later". Test: if you can swap in "perhaps", use this.
may be (two words) — the verb "may" + "be" — "it may be true"
altogether / all together
altogether (one word) — means "entirely / completely" — "altogether too expensive"
all together (two words) — means "all in one place or group" — "we sang all together"
anyway / any way
anyway (one word) — adverb meaning "regardless" — "I'll go anyway"
any way (two words) — noun phrase meaning "any method" — "is there any way to fix this?"
awhile / a while
awhile (one word) — adverb on its own, never after a preposition — "stay awhile"
a while (two words) — noun phrase, almost always after a preposition like "for" or "in" — "I'll be back in a while"
into / in to
into (one word) — a single preposition of motion — "she walked into the room"
in to (two words) — two separate words that just happen to sit next to each other — "in" ending a phrasal verb, followed by an unrelated "to" — "log in to your account", "turn your homework in to the teacher"
login / log in
login (one word) — noun or adjective — "enter your login", "the login page", "login credentials"
log in (two words) — verb phrase — "please log in to continue", "I can't log in". Test: if it follows "to" or comes right after a subject as an action, it's the verb — two words.
kickoff / kick off
kickoff (one word) — noun — "the kickoff is at 3pm", "a kickoff meeting"
kick off (two words) — verb phrase — "the match kicks off at 3pm", "let's kick off the meeting". Same test as login/log in: an action right after a subject is the verb — two words.
wake-up / wake up
wake-up (one word) — noun / adjective — usually hyphenated, rarely solid "wakeup" — "a wake-up call", "a wake-up call for the industry" (idiom: a shock that makes people realize something)
wake up (two words) — verb phrase — "wake up early", "I woke up at 7". Same test as kickoff/kick off: an action right after a subject is the verb — two words.
Memory aids
- · The trick for most of the "always one word" list: every-/no-/some-/any- + thing/one/body/where always compounds into a single word in modern English (everything, everyone, nobody, anybody...). "cannot" and "however" are separately-memorized exceptions, not part of this pattern.
- · The one deliberate exception to that rule is "no one" — it stays two words specifically so it is never misread as "noon". The rest of the "always two words" list (a lot, of course, in fact, at least, in order to, each other) are just short idiomatic phrases, not compound pronouns, so they never fuse.
- · "a lot" is always two words — "alot" is not a real word, one of the most common typos in English.
- · "misread" is always one word, never "miss read" — it's just the prefix mis- ("wrongly") added to "read", the same way "misspell" and "misunderstand" are one word. It also has the same two-pronunciation quirk as "read" itself (present tense rhymes with "need", past tense rhymes with "red") — see the Sound Gym page linked below.
