tituber

The French verb "tituber" means to stagger or to totter. It describes an unsteady walking movement, often due to dizziness, weakness, intoxication, or physical imbalance.

• Meaning: To move unsteadily as if about to fall; to wobble while walking.
• Example: Après avoir trop bu, il titubait en sortant du bar. (After drinking too much, he staggered leaving the bar.)

Synonyms and differences:

• trébucher: means "to stumble," usually referring to tripping over something and almost falling. It focuses on hitting an obstacle.
• vaciller: means "to wobble" or "to flicker," often used for both physical balance and non-physical phenomena like lights or decisions.
• chanceler: similar to "tituber," indicates swaying or losing balance, but can also suggest hesitation.

In short, "tituber" specifically conveys unsteady movement as if someone is trying to keep their balance but is not fully successful.
