Qual é a diferença entre endeavor e try e attempt ?Podes indicar apenas respostas exemplo.

An endeavor suggests that it is something that requires a greater effort in terms of minutely organizing and establishing the steps needed to achieve the goal; It's more time-consuming. While an attempt is something rather mechanic and with a more immediate effect: you go for it and you succeed or you fail.

For instance:
Finding the cure to cancer is a great endeavor -- i.e. it requires loads of time, many studies and experiencies...

Jumping this cliff is a dangerous attempt -- if you do it, you'll immediately know the result! whether it was actually dangerous or not.

Hope this could help.
