This question of mine has so far got three close votes and a slightly annoying dupe notice hanging around at the top of it when I am signed in:
This question is basically about why it is that the verb need appears to be a control verb [or Equi-deletion verb, if you prefer] when it's followed by an infinitival clause, whereas it works like a hollow clause verb [or a tough-movement verb, if you prefer that terminology] when followed by a gerund-participle clause.
Clearly, this calls for a discussion of gerund-participles. However, it has been linked to a supposed dupe which asks about the dialectical possibility of the verb need taking a past participle as a complement. There is no mention of gerund-participles (-ing forms of the verb) in the linked-to question at all. Here's the theoretical duplicate:
Especially if we see that a question has been asked by a reasonably seasoned or high rep user, could we be a little bit more careful about the duplicate voting, please.
I haven't edited my question in response to the duplicate close-votes. The reason being that I don't think it's helpful for the site to have explanations of why answers to a question about Father Christmas do not answer this here question about cabbages :D
