Your sentences above are correct, but intent in terms of being intent on doing something is not the same word as "intent," a noun, meaning something that is intended. I cannot think of any natural use of "to be intended," which means, to my mind, "intended to intend," which doesn't work.
If someone is "intended to go", that means that some other agent intends for that person to go. In that tweet of yours, the agent could be something like God, fate, or some other supernatural force or power: You are not intended to go = Fate/destiny does not intend for you to go.
Intended probably only works if it’s obvious who’s doing the intending. But it’s unreasonable, in my view, to expect us to comment on a whole list of possible combinations of basically the same sentence.
What are the difference between the following three sentences? 1) He intended to go to the Galapagos. 2) He intended to have gone to the Galapagos. 3) He had intended to go to the Galapagos. I think those sentences are very confusing!
No. That won't work. After "intended for" you need a noun, not a gerund. Here "use" is a noun. ...and intended for use in calculators. The writer could also have written: ...and intended to be used in calculators. I think "using" needs to be in an active clause, not an "intended for" passive clause: Intel planned on using the 4004 in calculators.
we were not intended to do what we did ???? and we didn't intend to do what we did ???? what is the difference between these two sentences ????
