ὀρθός

εὐθύς euthýs · G2117 · straight, direct, just

Both terms share the core sense of 'straight, direct,' applying in both physical and moral dimensions — both independently carry senses of moral rectitude as well as physical straightness. The distinction sometimes drawn between vertical and horizontal straightness is a matter of nuance within this shared core concept of straightness or correctness.

To live, to behave, to conduct oneself correctly41.30

This domain covers ὀρθός in its extended figurative sense of correctness, illustrated by the lame man's healing into an upright standing posture that pictures being properly restored: “he said with a loud voice, ‘Stand upright on your feet!’ And the man leaped up and began to walk.” (Acts 14:10)

Straight, direct79.88

Here ὀρθός describes literal physical straightness, as the writer of Hebrews urges believers to smooth the way for the weak: “make straight paths for your feet, so that the limb which is impaired may not be dislocated, but rather be healed.” (Hebrews 12:13)

Words formed from the same root. They share a form, not always a meaning.
