long

LAWNG/lɔːŋ/

Extending a substantial distance between its endpoints.

The long wooden plank lies beside a much shorter one.

Etymology

Old English lang already expressed considerable extent from end to end, so the modern spatial meaning continues directly. The same adjective also described time as extended in duration.
