   All in the wind (Naut.), a phrase denoting that the sails
      are parallel with the course of the wind, so as to shake.


   All told, all counted; in all.

   And all, and the rest; and everything connected. "Bring our
      crown and all." --Shak.

   At all.
   (a) In every respect; wholly; thoroughly. [Obs.] "She is a
       shrew at al(l)." --Chaucer.
   (b) A phrase much used by way of enforcement or emphasis,
       usually in negative or interrogative sentences, and
       signifying in any way or respect; in the least degree or
       to the least extent; in the least; under any
       circumstances; as, he has no ambition at all; has he any
       property at all? "Nothing at all." --Shak. "If thy father
       at all miss me." --1 Sam. xx. 6.

   Over all, everywhere. [Obs.] --Chaucer.
      [1913 Webster]

   Note: All is much used in composition to enlarge the meaning,
         or add force to a word. In some instances, it is
         completely incorporated into words, and its final
         consonant is dropped, as in almighty, already, always:
         but, in most instances, it is an adverb prefixed to
         adjectives or participles, but usually with a hyphen,
         as, all-bountiful, all-glorious, allimportant,
         all-surrounding, etc. In others it is an adjective; as,
         allpower, all-giver. Anciently many words, as, alabout,
         alaground, etc., were compounded with all, which are
         now written separately.
         [1913 Webster]
