Prefixes un- and dis-

    Knowing about prefixes is very useful in understandingand spelling some words - especially long words.
    Two common prefixes are un- and dis-, both meaning
            not, or the opposite of. 
    1. Here is the table from Prefix 2 with the gaps filled in:

    un + equal unequal dis + please displease
    un + foreseen unforeseen dis + order disorder
    un + likely unlikely dis + respect disrespect
    un + necessary
    		 unnecessary dis + service disservice
    un + official unofficial dis + place displace
    un + lawful unlawful dis + prove disprove
    un + dressed undressed dis + satisfied dissatisfied
    un + predictable unpredictable dis + comfort discomfort
    un + professional unprofessional dis + possess dispossess
    un + popular unpopular dis + similar dissimilar


    NOTICE that when the prefix ends with the same letter
    as the first letter of the base word then you have a double letter,
    for example:  dissimilar          unnecessary

    2. Now memorize the focus words and test yourself on them.
