Tricky Endings: -tion, -sion and -cian

Spell words ending in the “shun” sound.

Several endings sound like “shun”. The most common is -tion: station, action, invention. Use it when the root word ends in t or te: invent, invention; educate, education.

Use -sion when the root ends in d, de or se, or for words like television and explosion: explode, explosion; divide, division.

Use -cian for people's jobs when the root ends in c or cs: music, musician; electric, electrician; magic, magician.
