graben
Low (Technical Term)Formal, Technical (Geology, Earth Sciences)
Definition
Meaning
A long, narrow depression of the Earth's crust formed by the downward displacement of a block of land between parallel faults.
In geology, a specific type of rift valley. The term is also used, more rarely, in urban planning to describe sunken urban spaces, and metaphorically to signify a deep division or chasm.
Linguistics
Semantic Notes
The word is almost exclusively a technical term in geology. It is a loanword from German, where 'Graben' literally means 'ditch' or 'trench'. Its use outside of geology is highly specialized or metaphorical.

FAQ
Frequently Asked Questions
No, it is a low-frequency technical term used almost exclusively in geology and earth sciences.
No, in English 'graben' is only a noun (and can function attributively as an adjective, e.g., 'graben structure'). The German infinitive 'graben' means 'to dig', but this is not its meaning in English.
The opposite geological structure is a 'horst', which is a raised block of land between two parallel faults.
It is pronounced /ˈɡrɑːbən/, with a long 'a' sound as in 'father', not like the word 'grab'.
