Usage tips
Word structure
The word is made up of the negative prefix 'un-' and the adjective 'geduldig' (patient). 'Geduldig' comes from the noun 'die Geduld' (patience). So 'ungeduldig' literally means 'without patience'.
EXAMPLE
Sei nicht so ungeduldig, der Bus kommt gleich.
Don't be so impatient; the bus will be here soon.
Typical construction
When you wait impatiently for something, the fixed preposition 'auf' is used with the accusative. This pattern is very common.
EXAMPLE
Ich warte ungeduldig auf eine Antwort von der Universität.
I am waiting impatiently for a reply from the university.
State vs. process
You can use 'ungeduldig sein' (to be impatient) to describe a state. If you want to describe the process of becoming impatient, use the verb 'werden' (to become).
EXAMPLE
Die Kunden in der Schlange wurden langsam ungeduldig.
The customers in the line slowly became impatient.
Use as an adverb
'Ungeduldig' can also be used as an adverb to describe how an action is carried out. It then stands directly with the verb.
EXAMPLE
Er trommelte ungeduldig mit den Fingern auf den Tisch.
He drummed his fingers impatiently on the table.

antonym
ungeduldig vs ruhig
quiet / calm
'ruhig' and 'ungeduldig' often form a contrast, especially when waiting. A calm person stays composed and does not quickly become nervous. An impatient person finds it hard to wait and wants something to happen immediately. 'ungeduldig' often also shows irritation when something takes too long. If you are speaking generally about calmness, 'ruhig' fits. If the reason is waiting or a delay, 'ungeduldig' is an especially good opposite.
ungeduldig
Felix wird ungeduldig, weil das neue Programm so langsam startet.
Felix becomes impatient because the new program starts so slowly.
ruhig
Frau Demir bleibt ruhig, obwohl der Handwerker zu spät kommt.
Ms. Demir stays calm, even though the repairman is late.
