When I write proactively in my WinShell Latex editor, it underline it as a spelling error. My question is: is writing proactively correct? When shall I use pro-actively (with hyphen), and when I should not?

  • The editor is wrong. The hyphenated version is rare at best. Proactively is the right choice.

'Proactive', and by extension proactively, are correct. Pro-active and pro-actively were the norm in the past, using pro as a prefix to active. Whilst they are still correct to use today, over time, proactive and proactively became accepted into culture and into English dictionaries, and they are now the norm (and recommended to use).

Pr-oactively was never correct and is a spelling error
