Usage tips
Word formation
The word is made up of the prefix 'über-' (over-/too much) and the verb 'fordern' (to demand). The prefix 'über-' here means 'too much', so literally 'to demand too much'.
EXAMPLE
Die Menge an Informationen kann neue Lernende schnell überfordern.
The amount of information can quickly overwhelm new learners.
Inseparable verb
'Überfordern' (to overwhelm) is an inseparable verb. The prefix 'über-' is not separated from the verb stem in any sentence form.
EXAMPLE
Sie überfordert ihre Kinder mit zu hohen Erwartungen.
She overwhelms her children with expectations that are too high.
Participle as adjective
The past participle 'überfordert' (overwhelmed) is very often used like an adjective to describe the state of being overwhelmed. It often follows the verb 'sein' (to be) or 'sich fühlen' (to feel).
EXAMPLE
Nach acht Stunden Arbeit fühle ich mich total überfordert.
After eight hours of work, I feel totally overwhelmed.
Use with "mit"
To express what someone is overwhelmed by, the preposition 'mit' (with/by) is used followed by a noun in the dative.
EXAMPLE
Der Praktikant war mit der Verantwortung völlig überfordert.
The intern was completely overwhelmed by the responsibility.
Reflexive use
When a person expects too much of themselves, the verb is used reflexively with 'sich' (oneself). The reflexive pronoun is in the accusative.
EXAMPLE
Wenn du weiterhin 60 Stunden pro Woche arbeitest, überforderst du dich.
If you keep working 60 hours a week, you will overburden yourself.

überfordern vs fordern
to demand / challenge
'fordern' and 'überfordern' can both mean that a task needs energy, attention, or skill. The important difference is the limit. 'fordern' is often neutral or even positive: a task is difficult and requires effort. 'überfordern' means that it is too much and someone cannot manage it well. You can also overburden yourself with 'sich überfordern' when you take on too many tasks. The words are easy to confuse because both have to do with effort. Memory aid: 'fordern' means: it is demanding. 'überfordern' means: it is too much.
überfordern
Mit drei Projekten gleichzeitig überfordert sie sich im Moment.
With three projects at the same time, she is overburdening herself at the moment.
fordern
Der neue Kurs fordert viel Konzentration, aber Max lernt dabei schnell.
The new course demands a lot of concentration, but Max is learning quickly from it.
