  • [By a peculiar idiom, the adjective one was formerly used before the article the or an, or a pronoun, followed by an adjective, often in the superlative (as “one the best prince”), where now the pronoun one, followed by of and a plural noun (partitive genitive), would be used (as “one of the best princes”). Compare the idiom in “good my lord,” etc.

  • After an adjective, as substitute for a noun easily supplied in thought, especially being, person, or the like.
  • It easily passes, however, from the meaning ‘any one’ into the collective sense of ‘all persons,’ ‘people generally,’ and for this can be substituted people, they, we (if the speaker does not except himself from the general statement), you (the person addressed being taken as an example of others in general), or the impersonal passive may be substituted: as, one cannot be too careful (we cannot, you cannot, they cannot, people cannot be too careful); one knows not when (it is not known when). One is sometimes virtually a substitute for the first person, employed by a speaker who does not wish to put himself prominently forward: as, one does not like to say so, but it is only too true; one tries to do one's best. One's self or oneself is the corresponding reflexive: as, one must not praise one's self.

  • For CatKisses' list, lyrics that cover a good many possibilities for entering a room:

    She walks into a room and you know
    She's uncommonly rare, very unique,
    Peripatetic, poetic and chic.
    She walks into a room and you know
    From her maddening poise, effortless whirl,
    She's the special girl strolling,
    Can't help all of her qualities extolling
    Loaded with charisma is ma jauntily sauntering, ambling shambler,
    One,
    And you know you must shuffle along, join the parade,
    She's the quintessence of making the grade.
    This is whatcha call trav'ling
    Oh strut your stuff!
    Can't get enough!
    Ohh! Sigh! give her your attention
    Do I really have to mention
    She's the one!
