comma
A punctuation mark (,) used to structure sentences, separate parts of sentences, or list elements.
Vor dem Wort „aber“ steht in diesem Fall ein Komma.
Before the word 'aber' (but), there is a comma in this case.

In German, the comma is used as the decimal separator, not the period as in English. This is especially important with prices and units of measurement.
Das Buch kostet 19,95 € (neunzehn Euro fünfundneunzig).
The book costs €19.95 (nineteen euros ninety-five).
When reading a decimal number aloud, you say the word 'Komma' (comma). The number 3,14 is read as 'drei Komma eins vier' (three point one four) or 'drei Komma vierzehn' (three point fourteen).
Pi ist ungefähr drei Komma eins vier.
Pi is approximately three point one four.
When referring to the punctuation mark, the typical verbs are 'ein Komma setzen' (to put/place a comma), 'ein Komma machen' (to make a comma), or 'ein Komma weglassen' (to leave out a comma).
Ich bin unsicher, ob ich hier ein Komma setzen muss.
I'm not sure whether I need to put a comma here.
The idiom 'ohne Punkt und Komma reden' (to talk nonstop) is a fixed unit. It describes someone speaking very quickly and continuously.
Sie war so aufgeregt, dass sie ohne Punkt und Komma redete.
She was so excited that she talked nonstop.
point
'der Punkt' and 'das Komma' are both signs used in writing. As punctuation, the point usually ends a sentence, while the comma separates parts within a sentence. In numbers, the comma in German is also the sign between the whole number and the decimal part. Learners may mix up the words because both are small signs and often appear together in spelling. Pay attention to the function: point for an ending or a small mark, comma for separation.
