I’ve given plenty of examples in past posts. Here’s another example: try and. Consider the example sentence in the graphic above. It probably seems that the sentence is fine. And it would be in a context less formal than technical writing.
Try and is simply colloquial, and colloquial writing is less formal writing. What creates the lessened formality? It’s the exclusion of the word to that indicates the infinitive form of the verb. Omitting it in speech is fine since speech is typically less formal and the position of the infinitive verb within the sentence indicates its tense.
Seeing the words in writing communicates all of that, including the informal tone. More effective technical writing demands a more formal tone. Using the complete form of the infinitive verb helps to convey that formality.
