What this example shows

Latin puer means “boy”, and it is in the nominative case even though no ending is pronounced. To show that the case is there but silent, the source line writes an overt ø: puer-ø, glossed boy-NOM. The example is a small but precise case of marking something that has meaning but no sound.

A case with no sound

The noun and its silent case ending:

puer boy
The noun stem, “boy”.
NOM
The nominative case, present in the grammar but with no audible ending. The ø stands in for the missing form.

Why mark a zero

Some noun classes in Latin, Greek, and other languages mark a case by the absence of an ending rather than a visible suffix. Writing puer-ø with an overt ø keeps the gloss honest: the boy is a subject in the nominative, and the layout shows that even though nothing is pronounced. The matching hyphen count holds, one piece on each side.

Recreate it in the editor

Open the example and type the ø directly in the source line where a case is silent. Set the morpheme boundary character under Settings → Tokens so the stem and the zero split cleanly, then export the diagram as PNG, SVG, or PDF.
