▶ USAGE The traditional rule against placing an adverb between to and its verb – 'splitting the infinitive' – is gradually disappearing. Although it
is true that a split infinitive may result in a clumsy sentence (he decided to firmly and definitively deal with the problem), this is not enough to justify the absolute condemnation that this practice has
attracted. Indeed, very often the most natural position of the adverb is between to and the verb (he decided to really try next time) and to change it would result in an artificial and awkward construction (he decided really to try next time). The current view is therefore that the split infinitive is not a grammatical error.
Nevertheless, many writers prefer to avoid splitting infinitives in formal written
English, since readers with a more traditional point of view are likely to interpret
this type of construction as incorrect
