Usage tips
Word structure
The word "Köhler" (charcoal burner) is derived from the noun "die Kohle" (coal/charcoal). The ending "-er" here indicates a person professionally connected with something, similar to "Bäcker" (baker, from backen) or "Tischler" (carpenter, from Tisch).
EXAMPLE
Der Beruf des Köhlers war früher sehr wichtig für die Eisenverarbeitung.
The profession of the charcoal burner used to be very important for iron processing.
Context clue
You can tell from context whether the profession or the surname is meant. If the word appears with "Herr" (Mr.) or "Frau" (Ms./Mrs.), it is the name. If the topic is "Handwerk" (craft), "Wald" (forest), or "Holzkohle" (charcoal), the profession is meant.
EXAMPLE
Der alte Köhler erklärte den Kindern seine Arbeit.
The old charcoal burner explained his work to the children.
Cultural context
The profession of the charcoal burner is very rare in Germany today and has more of a historical or folkloric significance. You often find charcoal burners in open-air museums or at traditional festivals, but hardly ever as an everyday profession anymore.
EXAMPLE
