WordsWhat you are actually practicing
An affix is a small meaning carrier. -less contributes "without", -ful contributes "full of", re- contributes "again". Knowing what each one contributes lets you decode a word you have never seen — which is the single most useful vocabulary skill there is.
This game asks for the meaning directly, rather than asking you to pick a word that uses it.
How the game works
You are shown one affix and four meanings. Pick the meaning it contributes. A wrong pick reveals the correct one immediately.
Easy uses the most common affixes. Medium widens the set. Hard uses the full list, including pairs whose meanings are exact opposites.
The parts worth knowing
Negation: un-, dis-, anti- mean not, opposite, or against.
Time and order: re- again, pre- before, post- after.
Degree: over- too much, under- too little, semi- half.
Relation: sub- under, inter- between, bi- two, tri- three, multi- many.
Word class changers: -ful full of, -less without, -able can be, -er one who, -ness state of, -ly in the manner of.
Strategies that actually raise your score
Learn them in opposing pairs. -ful and -less, over- and under-, pre- and post-. Each pair is one unit of memory instead of two, and questions built on pairs become trivially easy.
Separate "word class" from "meaning". -ness and -ly do not add meaning so much as change what job the word does. If the options mix both kinds, decide which question is being asked first.
Use a word you already know as the anchor. For -less, think of homeless — no home. For -er, think of teacher — one who teaches.
Reject by category before meaning. If the affix is a prefix, an option describing a word class (one who) is probably wrong; prefixes almost always change meaning, not class.
