Prefix · quantity / excess
Signals excess or going beyond the normal limit: overwork, overlook, overcome, overtime.
Written by Bryan López, English teacher · Updated
Over- always signals excess: more than normal, more than desired, more than correct. With verbs it means doing something too much: overeat, oversleep, overcharge, overload. With adjectives and nouns it signals something that exceeds the expected level: overconfident, overtime, overpriced.
Over- also has a spatial meaning: above or across. overpass = a road that goes over another; overhead = above the head; overall = across everything. "Overcome" literally means to come over an obstacle. In everyday conversation, the excess sense is by far the more productive meaning to learn first.
Attaches directly to verbs, adjectives, and nouns:
No spelling change to the root. Stress falls on the first syllable: /ˈoʊvər/.

"Overcome" is used just as commonly with fears, grief, and abstract difficulties: overcome fear, overcome obstacles, overcome grief.
The spatial meaning ("a room overlooking the sea") is real but less frequent than the figurative sense of missing or ignoring something by accident.
A trick to remember it
Picture a scale tipping too far to one side. When a word has over-, something has gone past its normal limit: overwork = too much work, overload = too much load, overconfident = too much confidence. That image of excess works for almost every over- word.
