Key Concepts & Vocabulary

RootThe foundational morpheme of a word that carries its core meaning. It is the base to which prefixes and suffixes are attached.In the word 'transport', the root is 'port', from the Latin 'portare', meaning 'to carry'.
PrefixAn affix placed at the beginning of a word to modify its meaning.In 'transport', the prefix is 'trans-', from Latin, meaning 'across'. So, 'transport' means 'to carry across'.
SuffixAn affix placed at the end of a word to modify its meaning or change its grammatical function (e.g., from a verb to a noun).In 'portable', the suffix is '-able', meaning 'able to be'. So, 'portable' means 'able to be carried'.

If your inferred meaning doesn't make sense in the sentence, you may need to reconsider the specific connotation or a secondary meaning of a root.

Root + [i/o] + Root/Suffix
