Word: Magnesium
Part of Speech: Noun
Meaning: Magnesium means a light, silvery-white metal that burns with a dazzling white flame and is found in many foods.
Word origin: Comes through modern Latin from Magnesia, a district of ancient Greece.
Syllables: mag - ne - si - um
Tricky part: The ee sound in the second syllable comes from a single e, so students who go by the sound write magneesium or magnisium.
Watch out for: magneesium, magnisium, magnecium
Memory tip: Magnet gives you the start: keep its single e and do not add a second vowel beside it.
Example 1: Spinach and almonds are good sources of magnesium, so Amma adds both to our lunch boxes.
Example 2: Aircraft makers like magnesium alloys because they are strong yet very light.
Example 3: In the lab, Dev weighed the magnesium ribbon before placing it in the crucible.
The white chalk that gymnasts and rock climbers rub on their hands is magnesium carbonate, a compound of this metal.
