Spell Bee Word: oxygen


Basic Details

Word: Oxygen

Part of Speech: Noun

Meaning: A gas in the air with no colour or smell. People, animals and plants need it to live.

How to Spell Oxygen

Syllables: ox - y - gen

Tricky part: The middle vowel is y, not i, and the end is gen. Children often write oxigen.

Usage Examples

Example 1: Green plants give out oxygen during the day.

Example 3: A fire goes out when it runs short of oxygen.
