Usage tips
Word structure
The word is a compound of the preposition 'nach' (after) and the verb 'tragen' (to carry). A 'Nachtrag' (addendum/supplement) is therefore something that you 'carry' or add to a text or document afterward.
EXAMPLE
Bitte fügen Sie diese Information als Nachtrag hinzu.
Please add this information as an addendum.
Correct preposition
'Nachtrag' (addendum/supplement) is almost always used with the preposition 'zu' (to) and the dative to indicate what the addition belongs to.
EXAMPLE
Es gab einen Nachtrag zum Protokoll der letzten Sitzung.
There was an addendum to the minutes of the last meeting.
Context clue
The two meanings can be distinguished by context. If the Nachtrag refers to a 'Vertrag' (contract), 'Brief' (letter), or 'Text' (text), the general meaning (m01) is meant. In connection with 'Haushalt' (budget), 'Budget' (budget), or 'Finanzen' (finances), it refers to the special fiscal-policy meaning (m02).
EXAMPLE
Per E-Mail schickte er noch einen Nachtrag zu seinem Angebot.
He sent an addendum to his offer by email.
Register
The word 'Nachtrag' (addendum/supplement) belongs to formal language. It is used primarily in written, official, legal, or administrative contexts.
EXAMPLE
Der Notar verlas den Nachtrag zum Testament.
The notary read out the addendum to the will.
Compare with
confusable
Nachtrag vs Anlage
facility / attachment / investment
'die Anlage' and 'der Nachtrag' can both have to do with additional documents or parts of a text, but they do not mean the same thing. An 'Anlage' is attached to a letter or email, often from the beginning. A 'Nachtrag' is added later, when a text, document, or contract was already finished and still needs to be supplemented or corrected. Learners may confuse the words because both refer to something additional. Memory aid: 'eine Anlage' is enclosed; 'ein Nachtrag' is added afterward.
Nachtrag
Nach dem Gespräch schrieb die Firma einen Nachtrag zum Vertrag.
After the meeting, the company wrote an addendum to the contract.
Anlage
Bitte unterschreiben Sie den Vertrag und senden Sie auch die Anlage zurück.
Please sign the contract and also send back the attachment.
