angoro

Angoro is the heavy one. It is dread rather than fear: a tightness in the chest, often about nothing you can name, and often at four in the morning. The Latin root means squeezing, and the word has never really left that.

Be honest about the neighbours, because the boundaries are real but soft. Timi is to fear, and it takes an object: you fear something, a dog, a result, a person. Timo is the noun from it, the ordinary word for fear, and it is what you feel when there is a bear. Angoro usually has no object at all, which is exactly what makes it worse.

Maltrankvila is the everyday level down: uneasy, restless, not settled. Nervoza is jumpy and often temporary, the state before an examination. And zorgi is to worry in the practical sense, with a strong secondary meaning of taking care of something, so zorgo is a care or a concern rather than an emotion. Rough scale, weakest to heaviest: zorgo, maltrankvilo, timo, angoro.

The verb is angori, to be in anguish, and the adjective angora. For the existential flavour English borrows from German, Esperanto says angoro too, and ekzistotimo circulates in philosophical writing.
