        dispatch; hurry; precipitance; vehemence; precipitation.

   Usage: {Haste}, {Hurry}, {Speed}, {Dispatch}. Haste denotes
          quickness of action and a strong desire for getting
          on; hurry includes a confusion and want of collected
          thought not implied in haste; speed denotes the actual
          progress which is made; dispatch, the promptitude and
          rapidity with which things are done. A man may
          properly be in haste, but never in a hurry. Speed
          usually secures dispatch.
