An edge, in Hebrew, is קצה

, as in האור בקצה המנהרה

– the light at the end (edge) of the tunnel.

קצה

also appears in the expression, to live on the edge.

For example:

הוא תמיד מסתבך – הוא חי על הקצה.

He always gets into trouble – he lives on the edge.

קצה

is related to the word קצת

, which originally meant “a bit of…” before it became a word in its own right, not needing the “of…” part.
