Greek and Latin Roots for Word Meaning

希腊语和拉丁语词根与词义

Description

Use knowledge of Greek and Latin affixes (prefixes and suffixes) and roots as clues to determine the meaning of unfamiliar words, building a bank of common roots and their meanings

Mastery Evidence

✓ Identify common Greek and Latin roots in unfamiliar words and use root meaning to infer word meaning, e.g. 'aqua' (water) in aquarium/aquatic, 'dict' (say) in predict/dictionary
✓ Break a multi-morpheme word into prefix + root + suffix to determine meaning, e.g. un- (not) + believe + -able = not able to be believed
✓ Use knowledge of Greek-origin prefixes (auto-, tele-, micro-) and Latin-origin prefixes (inter-, trans-, sub-) to decode and define unfamiliar vocabulary in context

Assessment Prompt

If your child comes across an unfamiliar word containing a Greek or Latin root they recognise — like "port" in "transport" or "bio" in "biology" — can they use that to work out the meaning?
