“Think+Noun+good luck” vs “Think + Noun+ is good luck” [duplicate]
Solution 1:
The construction "VN+Adj" is well established for the verb "to think", as can be verified from OALD, 1, and so is "VN+N", although clarifications are needed about that latter.
- think somebody/something + adj.
♦ I think it highly unlikely that I'll get the job.
♦ She thought him kind and generous.
♦ It was better than I thought possible.- think somebody/something + noun
♦ I thought it a good idea to go with him.
However, the "VN+N" construction does not appear in the 2005 paper edition, and that is an indication, I think, of a less widely generalized applicability. For instance, sentences such as "She thought them students." do not seem to have much currency; "She thought they were students." is the normal way to say that. Therefore, some of those constructs are not very idiomatic, or, in any case, do not appear to be so to the native, or perhaps, simpler still, they have little possible meaning for anyone.
thought * a student
There is then a restricted set of noun phrases that will make acceptable combinations. My personal impression (very strong) is that nouns are very rarely used. The nouns "fool", "idiot" and "dreamer" are some of those rare instances.
- I thought him a(n) fool/idiot/dreamer.
thought * a fool, thought * an idiot, thought * a dreamer, …
The applicability becomes much wider when the noun phrases is not a plain noun but contains modifying elements, case for which there might still exist particular restrictions, but none is evident to me for the time being.
- thought him a very * ; replacements for X: man, gentleman, fellow, guy, person, physician, …
-
thought it a very good * ; replacements for X: plan, thing, idea, system, suggestion, cut flower and garden orange, …
