It wasn't a list of 'examples', it was a 'survey'. Although I admit I forgot about 'doubt' when I did my conclusion.Pabappa wrote: ↑25 Jul 2020 16:08surprised you added "doubt it" to the list, as i would call that a counterexample.
some other possible counterexamples show up in the past tense .... "loved it!" ... "got it!" ... "crushed it!" .... but only the doubt verb carries inherent 1st person in the present tense.
So, I'm OK with, in a colloquial sense, saying that 'love it', 'want it', 'hate it' and 'doubt it' can all carry an implicit first person singular pronoun, as can 'promise' without an object.
Although it's then worth pointing out that if we look at the most syntactically, as well as morphologically, unmarked forms, by taking out the object pronoun altogether, we do gain 'promise', but we lose 'doubt' and 'love'. We keep 'hate!' and 'want!' (for 'I hate it' and 'I want it'), but only in an even more colloquial register.
So this effect only works with certain verbs, in somewhat unpredictable ways (why does it work with 'doubt it' and 'promise!' but not 'doubt!' and 'promise it'?; why is 'like it!' just about possible but 'dislike it!' isn't? Even though, say, "do not like!" is arguably possible?), and in most cases only in very colloquial registers, with possible variation with dialect. And overwhelmingly found in interjections and responses, rather than full sentences, and typically associated with the expression of strong feelings.
In other words, these are a handful of parallel idiomatic expressions, and in no way the 'default' sense of the verb form.
