    • Confusingly, there are also cases where both forms are considered acceptable (British: pre-school / American: preschool). As can be seen from this last example, the tendency in American English is to hyphenate less than in British English.
    • In all events, if in doubt about whether a prefix should be followed by a hyphen, consult a reliable dictionary.

    • Words beginning with a common prefix (such as un-, dis- or re-) are often written without a hyphen

      a little-discussed problem
      a low-prevalence phenomenon
      a well-meaning intervention

    • However, do not hyphenate compound adjectival forms in which the first element is an adverb ending in either -ly or in -y.
