✅ Acquaintance is the perfect word for a person with whom you have contact, but don’t know intimately (She considered him a casual acquaintance because she saw him each day at the café).
✅ Friend implies a more intimate relationship than acquaintance, one in which you have warm affection for the other person (a trusted friend; a family friend), but friend does not necessarily imply shared activities or conditions like past Synonym of the Day companion.
✅ Friend contrasts with foe in literary writing (Friend or foe?) or even with its synonym acquaintance to distance oneself (He was merely an acquaintance, not a friend).
Thanks for being a friend of Synonym of the Day!
