giga-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: A borrowing from Greek. Etymon: Greek γίγας.

Etymology: < ancient Greek γίγας giant n.

An arbitrary derivative of Greek γίγας giant, prefixed to the names of units esp. in the metric system to form the names of units 1000 million (10⁹) times greater. Abbrev. G.
