What does someone want or plan to do?
grammatical mood
משמעות
Wanting and intending show what someone wishes for or plans to do. A wish need not become a plan, and a plan need not lead to action. Some languages have special verb forms for wishes or intentions; others use ordinary words and context. Past, present and future tells us when an event happens, not whether someone wants it to happen.
איך לזהות
Look for a wish, plan, willingness, or refusal, rather than just a statement that an event will happen.
