Word Meaning

CCSS.ELA-Literacy.L.3.4b Determine the meaning of the new word formed when a known affix is added to a known word (e.g., agreeable/disagreeable, comfortable/uncomfortable, care/careless, heat/preheat).
An affix is a word part that is added to the beginning (prefix) or ending (suffix) of a word to change its meaning. Affixes can help you know what a word means.
