I'm studying about Infinitive topic. The website tells me that some element in this sentence is dropped. I think the full sentence is "He helped me write the Program" but I don't understand the rule that is used to drop some element in the sentence.
In constructions involving the verb to help, it's perfectly natural (but not obligatory) to "delete" the infinitive marker to before the relevant verb identifying the action for which assistance was provided...
He helped me [to] write the program
There's more background on this use of to help [someone] [to] do something in the ELU question What is the correct way to use infinitive after the verb “help”: with or without “to”? (which was asked some years before this ELL site was created).
I'd be interested to know if anyone can come up with any alternative verbs instead of write above that would both make reasonable sense and either require or disallow the infinitive marker to.
