S'éloigner vs. s'écarter
These two French reflexive verbs describe the act of moving away, but they differ in direction and intent. Generally, séloigner' emphasizes increasing the distance between two points (going far), while sécarter' emphasizes moving to the side or deviating from a path (stepping aside).
S'éloigner
A2This verb comes from the word loin (far). It means to go further away from a point of origin, increasing the physical or emotional distance, often until the object is barely visible or gone.

(The boat is slowly moving away from the coast.)

S'écarter
B1This verb stems from écart (gap or interval). It means to move to the side, to step aside to create a passage, or to deviate/stray from a specific rule, subject, or line.

Summary
Use séloigner' when the focus is on distance and going far away from something. Use sécarter' when the focus is on lateral movement, stepping aside to make room, or diverging from a set path or topic.
