✕Common Mistakes
Er nicht ist erreichbar.
The negation 'nicht' must come before the adjective, not between the verb and the adjective.
Er ist erreichbar nicht.
In German the negation 'nicht' precedes the adjective; placing it after sounds unnatural.
Er ist nicht erreichbares.
The adjective stays in its base form after 'sein'; do not add an ending.

Cultural Tip
In German business communication it’s common to add a time reference, e.g., 'Er ist momentan nicht erreichbar' or to give a reason, such as 'Er ist im Urlaub und nicht erreichbar.' Avoid overly informal phrasing in professional emails; keep the tone neutral and concise.
