This is a simple function that tests for non-alpha characters in a word. May not be the most efficient, but it does work.

Code:
# returns good (0) if the word contains only alpha chracters
function word_ok
{
        case $1 in 
                *[^a-zA-Z]*)    return 1;;   # return bad if word contains any non-alpha
        esac

        return 0
}

# example usage:
if word_ok $1
then
        echo "word is ok: $1"
else
        echo "word is bad: $1"
fi

Hope this helps.
