Ability to


Hi, I'm confused with the usage of "ability to". I read a sentence: "I witness her improvement in her ability to develop creative ideas and to think logically". I think the second to is redundant and can be left out. I'd like to know whether the original sentence was correct. Thanks in advance.

    The second 'to' is meaningful, because without it, the sense could be 'think logically as a result of, or as part of, the development of creative ideas'.

    However, as the sentence stands, creativity and logic are seen as separate processes and abilities. This makes the meaning precise instead of ambiguous.

    The sentence is grammatically correct both with and without the second "to".
    Especially in writing, the second "to" creates parallelism between the two abilities and helps the reader understand the structure of the sentence.
    When the two phrases linked by "and" are short, the second "to" is not so important; when they are long, it becomes more important to include it.
