wobei (whereby, although, in which)

What "wobei" means

"wobei" is a subordinating conjunction (Subjunktion). It attaches a second clause to the main clause and covers two closely related jobs:

1. Accompanying circumstance / result - "whereby", "in the course of which", "with ... doing". It describes something that happens alongside or as a consequence of the main action.

• Man mischt Mehl und Wasser, wobei ein zäher Teig entsteht. - "You mix flour and water, whereby a sticky dough forms."

2. Soft restriction or contrast - "though", "although", "whereas", "mind you". It adds a qualifying remark that limits or slightly contradicts the main clause.

• Der Vortrag war interessant, wobei er etwas zu lang war. - "The lecture was interesting, though it was a bit too long."

Form and word order

"wobei" is a fused form of wo + bei and behaves like a relative adverb, but for learners the key point is grammatical, not morphological: it is subordinating, so

• a comma always comes before it, and
• the finite verb goes to the very end of the "wobei" clause.

`` Hauptsatz, wobei + Subjekt + (weitere Satzglieder) + finites Verb. Das Auto ist alt, wobei der Motor noch gut läuft. ``

"wobei" does not decline and takes no case of its own - it is a connector, not a preposition, so nothing after it changes case because of it. (Do not confuse it with the two-word question "Wobei hilfst du?" = "With what are you helping?", where "wo(r)bei" is an interrogative.)

When to use it

• To append an afterthought, a caveat, or a limiting comment in speech and writing: Das Angebot ist gut, wobei ich noch vergleichen möchte.
• To describe a simultaneous or resulting process, common in instructions and reports: Sie renovierten das Haus selbst, wobei sie viel Geld sparten.
• It is slightly more written/neutral than starting a new sentence with "Allerdings ...", but it is fully idiomatic in everyday spoken German too.

Most common mistake

Learners keep verb-second order, as if "wobei" were a coordinating conjunction like aber:

• Wrong: ..., wobei er hat die Bedingungen kaum gelesen.
• Right: ..., wobei er die Bedingungen kaum gelesen hat.

Remember: "wobei" opens a subordinate clause, so the conjugated verb is the last word.

"wobei" is a subordinating conjunction that adds a comment, restriction, or accompanying circumstance to the main clause; it sends the finite verb to the end of its clause and translates as "whereby", "though/whereas", "during which", or "with ... doing".

"wobei" links a second clause to the main clause and can mean "whereby / in the course of which" (a result or accompanying circumstance) or "though / whereas" (a soft restriction or contrast). Either way it is subordinating, so a comma comes before it and the conjugated verb moves to the end: "Das Handy ist teuer, wobei die Kamera hervorragend ist."

"wobei" ist eine unterordnende Konjunktion (Subjunktion), die dem Hauptsatz einen Kommentar, eine Einschränkung oder einen Begleitumstand hinzufügt; das finite Verb steht am Ende des Nebensatzes. Es entspricht "whereby", "wohingegen/obwohl", "während" oder "wobei ... zugleich".
