No variable slots; the word is fixed and can be combined with any verb to express simultaneity.

• arbeiten
• stattfinden
• passieren
• laufen
• existieren
• nutzen

• zur gleichen Zeit (neutral)
• parallel (emphasizes independent processes)
• zeitgleich (formal)
• simultan (technical
• from Latin)

The adverb is often placed incorrectly, e.g., *Er arbeitet gleichzeitig das Projekt* instead of *Er arbeitet gleichzeitig an dem Projekt*. Also, the verb 'sein' is sometimes used without a complement: *Er ist gleichzeitig* (incomplete).

zur gleichen Zeit, parallel, zeitgleich, nacheinander, hintereinander

Learners whose L1 is English may be tempted to translate 'simultaneously' directly, but German prefers the adverb 'gleichzeitig' without a preposition. Overusing 'zur gleichen Zeit' can sound redundant.

• gleichzeitig
• gleichzeitig mit
• zur gleichen Zeit
• zur selben Zeit

‘gleichzeitig’ is neutral and appropriate in most contexts; it sounds slightly more formal than ‘parallel’, which is used more for independent processes.

Using ‘gleichzeitig’ signals that multiple actions or states are proceeding in coordination, enhancing clarity in conversation.

same time

‘gleichzeitig’ can be used in both everyday and technical contexts and typically appears before the verb or at the end of the sentence.
