What other words can

bio?
Some roots form whole words by
themselves. For example: audio
means "sound" or "hearing."
Although these roots form words in
and of themselves, you can also
combine them with other word
elements (like prefixes and suffixes)
to make new words, as in the
following: audiologist
( a person who checks your
hearing)
Some roots must be
combined with other word
elements to form words.
Prefixes and suffixes alter or
refine a word's meaning. For
example, the word audible
means "able to be heard."
With the prefix in-, the word
becomes inaudible, which
means "unable to be heard."
A word can contain more
than one root. For example,
Audiometry (from the Latin
audīre, "to hear" and metria, “to
measure”) is the science of
measuring hearing acuity for
variations in sound intensity and
pitch.
