I came across the line, "he went on explain (a metaphor) in the clip," at the end of the following sentence of the article, "How to insult your political opponents" appearing in New Yorker magazine (May 3).
"Crucify is kind of like how the Romans used to conquer villages in the Mediterranean- they'd go into a little Turkish town somewhere and they'd find the first five guys they saw and they'd crucify them," the official, Al Armendariz, said in a speech he gave in 2010. "Then that little town was really easy to manage for the next few years."
This was a metaphor for the deterrent effect the E.P.A. was going for, "he went on explain in the clip."
I was in understanding that "go on" is followed by "to + infinitive" or gerund.
Can "go on" take a verb root as its objective or complement? Is it right to say "he went on speak a gossip," "she went on play piano," "I went on write a letter"?
Conversely, are "he went on speaking/playing/writing," or "he went on to speak/to play/to write" wrong?
