The collector stored the rare D-marks in a climate-controlled safe.

He kept an old D-mark coin as a souvenir from his trip to Berlin.

In the lab report she wrote D/L-serine to denote the stereoisomeric form in the sample.

I can't believe he called me a d*ck during the meeting.

Can you D/L the presentation before the meeting starts?

I started the D/L before leaving so it would finish by the time I returned.

Please d/l the file from the server before the meeting.

I started the d/l but it stalled halfway through.

I found several d*cks carved into the old oak tree, much to my surprise.

The rust along the D-post required immediate attention to prevent structural damage.
