使用する際の注意点

• Whether it is proper to use "firstly", rather than "first", has often been disputed.
  • Beginning in the early 19th century, some have argued against the use of "firstly", advocating the sequence: "First", "secondly", "thirdly", ....
  • The usage of "firstly" is also deprecated by some modern style guides.^[2] The Chicago Manual of Style further recommends that all such -ly forms be avoided, and that list items begin only with "first", "second", and so forth.^[3]
  • Other authorities disagree.
    • The American Heritage Dictionary comments:

      It is well established that either first or firstly can be used to begin an enumeration: Our objectives are, first (または firstly), to recover from last year's slump.^[4]

    • The Oxford English Dictionary notes the dispute but does not pass judgment: "many writers prefer first, even though closely followed by secondly, thirdly, etc."^[5]
  • "Firstly" may appear more formal than "first" and is often recommended for the formal enumeration of arguments.^[6]
