N,O

 

No one
Two words, no hyphen.

Numbers

  • write from one to nine in full, and 10 upwards as numerals, but be consistent within a sentence: 'The number injured rose from eight to fourteen'
  • write out millions from one to nine in full and thereafter 10 million, etc
  • use the form 8.5 million rather than eight-and-a-half million. However, this is not the case for monetary values (see previous section). Use £8.5m
  • insert a comma in numbers in the thousands, ie 75,000
  • if a number starts a sentence, write it out in full (Thirty-four, for example) except where it starts a title or subheading
  • numbers written out in full should be hyphenated eg twenty-two.

Online
One word, no hyphen.

Only
Can be ambiguous if not placed next to the word or phrase modified: “I have only one ambition” is clearer than “I only have one ambition”.

Say “the only” or “one of the few” rather than “one of the only”.

Outpatient
No hyphen.
