Prefixes un- and dis-

    Knowing about prefixes is very useful in understanding and spelling some words - especially long words.
    Two common prefixes are un- and dis-, both meaning
            not, or the opposite of. 
    1. Fill in the gaps in the following table:

    un + equal unequal dis + please displease


    		 unforeseen dis + order

    un + likely



    		disrespect

    		 unnecessary dis + service

    un + official

    		dis + place

    un + lawful



    		disprove

    		dissatisfied
    un + predictable

    		dis + comfort

    unprofessional

    		dis + possess

    un + popular



    		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
