Spelling Skills # 6 - Prefixes

American spelling: prefixes

Here are some spelling rules for applying prefixes to root words:

Words have been categorized in grammar on how they are used, or as parts of speech:
verb, noun, pronoun, adjective, adverb, preposition, conjunction, and interjection.
Words also have "roots" which convey their basic meaning. Prefixes are groups of letters (afixes!) placed before a root word to form a new word, change its part of speech, and/or modify its meaning. For example:
ante (prefix) + date (noun) = antedate (verb or noun) to assign a time before its occurence.
auto (prefix) + biography (noun) = autobiography (noun) a self-written biography.
trans (prefix) + nation(al) (noun) = transnational (adjective), across nations.
un (prefix) + happy (adjective) = unhappy (adjective) a "not" happy state
un (prefix) + finished (adjective) = unfinished (adjective) in a not completed state
pre (prefix) + board (verb) = preboard (verb) as for families with children boarding a flight before other passengers
mis (prefix) + spell (verb) = misspell (verb) to not spell correctly!
anti (prefix) + clockwise (verb) = anticlockwise (verb) to go in the opposite direction of the hands of a clock
re (prefix) + consider (verb) = reconsider (verb) to review or consider again
